find the value of angel 0 to the nearest 10th
Answer: 36.9
Step-by-step explanation:
For this question you have to find out whether you are using Sin, Cos or Tan.
To work out which one you are using you can use SOH CAH TOA to help you.
SOH- The 'S' is for Sin, the 'O' and the 'H' is for Opposite over Hypotenuse.
CAH- The 'C' is for Cos and the 'A' and the 'H' is for Adjacent over Hypotenuse.
TOA- The 'T' is for Tan, the 'O' and the 'A is for Opposite over Adjacent.
As you have the Opposite (the side opposite the angle we're looking for) and the Adjacent (the side next to the angle were looking for) we would be using Tan.
So first you would have to write:
Tanθ=3/4
Then because we want Theta (θ) on it's own we would have to do the inverse to 'undo' the equation. Tan-1 is the inverse of Tan.
θ=Tan-1 3/4
To find the answer you would have to put it in your calculator.
θ=36.9

Step-by-step explanation:
does 13, 12, 6 form a pythagorean triple?
Answer:
No
Step-by-step explanation:
the pythagorean theorem is
a^2+b^2=c^2
These numbers do not fit in these terms
Answer:
It doesn't.
Step-by-step explanation:
In order for something to be a {ythagorean triple, it must comply with the Pythagorean theorem, which is a² + b² = c²
Always remember, when plugging in the values into that equation, the exponent of two means to square the number, and a and b have to be the two smallest values (in this case, 6 and 12)
6² = 36
12² = 144
36 + 144 = 180
Now, we have to find if ti equals c². 13² equals 169
Therefore, 180 ≠ 169, therefore it IS NOT a Pythagorean triple.

A store has a sale for 25% off. You want a sweater that usually cost $30. How much money will you spend on the sweater?
Answer:
you will spend $22.50 on the sweater
Step-by-step explanation:
just multiply 30 by 0.25 and subtract the product from the original value
30 * 0.25= 7.50
30-7.50= 22.50
what multiple of 9 is a factor of 9
Answer:
9
Step-by-step explanation:
Answer:
( 1 ), ( 3 ), ( 9 )
Step-by-step explanation:
Every time you add one to a digit (which is the same as adding 10, 100, 1000, etc) you get a number that is one more than a multiple of 9, so you have to subtract one from the number, which brings the sum of the digits back to 9.

A triangular garden has angles of 80, 50, and 50. If the longest side is 40 feet, what is the length of the remaining sides?
Answer:
the other two sides are 31.11 feet and 31.11 feet
Step-by-step explanation:
since two angles are 50°, the triangle is isosceles with the other two sides being equal in length.
A right triangle is formed by a line from its peak down & perpendicular to
the 40 foot side. It's hypotenuse is the unknown (x) and it's base is 40/2 = 20 feet.
cos 50 = 20/x
0.6428 = 20/x
x = 31.11 feet

Answer:
Step-by-step explanation:
|14-(6-x)| = |14-6+x| = |8+x|
|8+x| = 8+x if x > -8
|8+x| = -x-8 if x < -8
|8+x| = 0 if x= -8

What statement about the volume of the cylinder and cone is true ?
Answer:c
Step-by-step explanation:
What is the solution to the equation?
Answer:
Step-by-step explanation:
[tex]\sqrt[3]{x+4}+\sqrt[3]{2x +8}=0\\\\\sqrt[3]{x+4}= -\sqrt[3]{2x + 8}\\\\(x +4)^{\frac{1}{3}}=-(2x+8)^{\frac{1}{3}}\\\\[/tex]
Take cube,
[tex][(x+4)^{\frac{1}{3}}]^{3} =- [(2x +8)^{\frac{1}{3}}^{3}]\\\\(x+4)^{3*\frac{1}{3}}=-(2x + 8)^{3*\frac{1}{3}}\\\\[/tex]
x + 4 = - (2x + 8)
x +4 = 2x *(-1) + 8 *(-1)
x+ 4 = -2x - 8
x +2x+4 = - 8
3x + 4 = - 8
3x = - 8 -4
3x = -12
x = -12/3
x = -4
Triangle 1 has vertices at (A,B), (C,D), and (E,F). Triangle 2 has vertices at (A+1,B+3), (C+1,D+3), and (E+1,F+3). What can you conclude about triangle 2?
Given:
Triangle 1 has vertices at (A,B), (C,D), and (E,F).
Triangle 2 has vertices at (A+1,B+3), (C+1,D+3), and (E+1,F+3).
To find:
The conclusion about the triangle 2.
Solution:
From the given information it is clear that the x-coordinates of the vertices of triangle 2 are 1 more than the x-coordinates of the vertices of triangle 1.
Similarly, the y-coordinates of the vertices of triangle 2 are 3 more than the y-coordinates of the vertices of triangle 1.
So, the rule of translation is:
[tex](x,y)\to (x+1,y+3)[/tex]
It means the triangle 1 is shifted 1 unit right and 3 units up to get the triangle 2.
Therefore, triangle 2 is congruent to triangle 1 and triangle 2 is the translation of triangle 1 by 1 unit right and 3 units up.

Answer:
72.25
Step-by-step explanation:
12.5 x 8.5 = 106.25
5 x 6.75 = 33.75
106.25- 33.75 = 72.25
Answer: H
Step-by-step explanation:
You're tryna find the area of the wall
Which is the whole surface area minus the door's area
Whole surface area = 8.5 x 12.5 = 106.25
Door area = 5 x 6.75 = 33.75
106.25-33.75 = 72.5 ft^2

(PLS make a big paragraph thanks)
Answer:
PEMDAS
Step-by-step explanation:
Use PEMDAS. Parenthesis, Exponents, Multiplication/Division, Addition/Subtraction.
Start with your parenthesis, which is (9-6). This comes out to 3. Your equation should now look like 2+(3)x5/3
Then, go to your exponents. Since we don't have any, we skip this step.
Now, we look from left to right for any multiplication symbols or division symbols. Finding (3)x5, this comes out to 15. Now rewrite your equation, if should look like this: 2+15/3.
Repeat the last step and find your division symbol, and find this 15/3. That comes out to 5.
The last step is finding addition or subtraction symbols, and since there's only two numbers left we can just solve the problem from here.
2+5=7.

You buy a car for $25000. It lose 14% of its value every year. Sally wrote a function that represents the value of the car after t years. V(t)=25000(1.14)t Describe and correct the error
Answer:
Correct answer
V(t) = 25000(0.86) t
Step-by-step explanation:
You wont turn 14% into a multiplier (1.14 - multiplier) becuase the value decreases not increases so you do 100% - 14% to get 86% and divide by 100 to get 0.86...that's the value that goes in the brackets
