Plot the point (-7, -5). We are in quadrant 3.
We also know that tan θ = opp/adj.
Cot θ = adj/opp.
Let us use a^2 + b^2 = r^2 to show you how to find r, the radius aka hypotenuse.
Look: (-7)^2 + (-5)^2 = r^2
If you should ever need to find r, do this:
(-7)^2 + (-5)^2 = r^2
(49) + 25) = r^2
74 = r^2
Take the square root on both sides of the equation to find r.
sqrt{74} = sqrt{r^2}
sqrt{74} = r
It is ok to simplify the sqrt{74} but not needed.
We now have the three sides of the triangle that is form in quadrant 3.
We can now read cot θ from the triangle itself.
So, cot θ = adj/opp = (-7)/(-5) or 7/5.
No need to find r but I simply wanted to show you how it's done in case you are given a question where r must be found.

What is circle?A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “centre”. The perimeter around the circle is known as the circumference.
here, we have,
we know that,
A secant is a line which intersects a circle at exactly two different points and leaves a chord on joining those two points.
again, we know,
A chord is a line which which terminates on the two different points on the circle.
and, we have,
Radius is the line joining the center to any of the point on the circle.
we know,
Tangent is a line which crosses from the outer periphery of the circle touching at any of its one point.
we get,
Thus the secant in the given diagram is clearly none other than XY.
Hence, The solution is : D. XY, is of the segments below is a secant.

The perimeter of a rectangle is represented by the expression 6x + 4. If the width of the rectangle is represented by the expression x – 1, which expression represents the length? 4x + 6 4x – 6 2x + 3 2x + 6
Answer:
2x + 3
Step-by-step explanation:
two sides measure (x-1) which gives 2(x-1) or 2x - 2
subtract 2x - 2 from 6x + 4 to get 4x + 6
4x + 6 represents twice the length so divide it in half to get:
2x + 3
Answer:
The perimeter of a rectangle is represented by the expression 6x + 4. If the width of the rectangle is represented by the expression x – 1, which expression represents the length?

Factor the following trinomials. Place each factor in its own blank. You do NOT need to put
parenthesis, just put one binomial (WITHOUT SPACES) into each blank.
X^2+ 13x + 36
Answer:
(x+9)(x+4)
Step-by-step explanation:
We wish to factor x²+13x+36 into the form of (x+p)(x+q) where p+q=13 and pq=36.
Factors of 36: 1, 2, 3, 4, 6, 9, 12. 18, 36
Notice that 9+4=13 as 9*4=36, which satisfies the values of p and q
This means x²+13x+36 can be factored into (x+9)(x+4)
I need help on finding the perimeter of MNP. I do not know how to start this problem. Any help will be appreciated :)
Answer:
The perimeter of triangle MNP is 130 units
Step-by-step explanation:
By the mid segment theorem, we have it that the a side of the smaller inner triangle is 1/2 the measure of the parallel side of the bigger triangle that faces it
This mean RS is half MN, QS is half NP and QR is half MP
Using this, we have it that;
2(x + 4) = 5x - 34
2x + 8 = 5x -34
5x-2x = 34 + 8
3x = 42
x = 42/3
x = 14
So we have RS which is x + 4 as 14 + 4 = 18
The perimeter of the smaller triangle is the sum of its side lengths
We have this as;
22 + 25 + 18 = 65
Furthermore, by the mid segment theorem , the perimeter of the bigger triangle is twice that of the smaller
thus, we have the perimeter of MNP as 2(65) = 130 units

What are congruent triangles?If two triangles have the same size and shape they are called congruent triangles. If we flip, turn or rotate one of two congruent triangles they are still congruent. If the sides of two triangles are the same then the triangles must have the same angles and therefore must be congruent.Given is a parallelogram as shown in the image.
In order to prove ABCD as a parallelogram, we can prove ΔABE and ΔCDE congruent to each other by Angle - Angle - Side congruent property as -
∠BAE = ∠DCE {Alt. int. angles}
∠ABE = ∠CDE {Alt. int. angles}
AB = CD {Given}
Therefore, she can prove ABCD as a parallelogram by proving -
ΔABE ≅ ΔCDE using AAS criteria.

The ratio of seventh graders to sixth graders on a chess team is 5 to 3 . What is the ratio of seventh graders to total chess players ? Enter the correct answer in the box
Answer: 5 : 8
Step-by-step explanation:
The ratio of seventh graders to sixth grader on the team is 5 : 3.
Assuming that only seventh and sixth graders are in the team, the total number of chess players at the most simple basis is:
= Number of seventh grade students in ratio + Number of sixth grade students in ratio
= 5 + 3
= 8 students
There are 5 seventh graders so the ratio will be:
= 5 : 8
Note: The chess team will most likely have more than 8 members but the ratio of seventh graders to total chess players will still be 5 : 8.
Haley is watching a movie that is 120 minutes long she draws this bar model to show 120 minutes divided into ten groups if Haley has watched 40% of the movie how many minutes has she watched?
Answer:
48 minutes
Step-by-step explanation:
take 40/100 and ?/120
we have to figure out what "?" equals
120*40= 4800
divide 4800 by 100 becuase that is the maximum percentage
4800/100= 48
40/100 = 48/120

Find the volume of the sphere. Round your answer to the nearest tenth.
Help me please
Answer: The closest one would be 3052.1
Step-by-step explanation:
Which one is larger: The surface area of a sphere with
radius r inches or the combined area of three circles
each of radius r inches? How do you know?
Answer:
Step-by-step explanation:
formula for surface area of a sphere is
A = 4πr^2
for a circle the area is
A = πr^2
notice they are the same except for the 4 in front of the sphere... so which do you think is bigger
3 circles or 1 sphere.. that all have the same "r" ???
it's the sphere.. if you're really not sure
State whether segments of the given lengths can be side of a right angle triangle.
a=7, b=24, and C=25.
Show working to support your answer. *
2 Points
Given:
In a triangle,
[tex]a=7,b=24,c=25[/tex]
To find:
Whether the given segments are the sides of a right triangle or not.
Solution:
In a right triangle the square of largest side is equal to the sum of squares of two smaller side.
[tex]c^2=a^2+b^2[/tex] (Pythagoras theorem)
Three sides are [tex]a=7,b=24,c=25[/tex]. Here, 25 is the largest side.
[tex]25^2=625[/tex]
Now, the sum of squares of two smaller sides is:
[tex](7)^2+(24)^2=49+576[/tex]
[tex](7)^2+(24)^2=625[/tex]
[tex](7)^2+(24)^2=25^2[/tex]
Since the sum of squares of two smaller side is equal to the square of largest side, therefore the given segments are the sides of a right triangle.

Need to keep cell bill under 60.,monthly charge is 30. And texts are 0.05 each. Write an inequality to represent the # of texts she can have
Answer:
[tex]30 + 0.05x < 60[/tex]
The number of texts she can have is less than 600.
Step-by-step explanation:
Total monthly charge
30 + 0.05 for each text.
So, for x tests, the charge is:
[tex]C(x) = 30 + 0.05x[/tex]
Write an inequality to represent the # of texts she can have?
It has to be under 60, so:
[tex]C(x) < 60[/tex]
[tex]30 + 0.05x < 60[/tex]
The solution is:
[tex]0.05x < 30[/tex]
[tex]x < \frac{30}{0.05}[/tex]
[tex]x < 600[/tex]
The number of texts she can have is less than 600.

All the triangles have 180° total angle measurement.
First question:
114 + 37 + x = 180°
151 + x = 180
x = 180 - 151
x = 29°
Second question:
93 + 46 + x = 180
139 + x = 180
x = 180 - 139
x = 41°
Answer:
In the first question x=29 Because the interior of a triangle adds up to 180.So you will add 114+37=151 , 180-151=29
The second question 93+46=139
180-139=41
x=41
