Answer:
Step-by-step explanation:
take angle A as reference angle
using cos rule
cos A=adjacent/hypotenuse
cos A=12/13
cos A=0.92
A=cos 23
A=23 degree
for ratio,
cos A=12/13
Cos( A ) = AC / AB [ Ratio ]
Cos( A ) = 12 / 13 [ Ratio ]
Cos( A ) = 0. 92307 [ Exact value ]

What is the probability of picking a 5 and then picking a 4?
Find the value of x please I need help
Answer:
Step-by-step explanation:
113+90+90+12x+7=360(sum of four angles is always 360 degree)
300+12x=360
12x=360-300
x=60/12
x=5
Answer:
X = 5
Step-by-step explanation:
Shapes with 4 sides have angles that add to 360 degrees
So you have two right angles and 113 degrees.
This is
90+90+113=293
360-293=67
12x5=60
60+7=67
This means that x=5
What number has a value less than 14.7?
Answer:
Anything below 14.7
Step-by-step explanation:
here is the more clearer picture!!!!
Answer:
angle FDA = 75 degrees
angle JAI = 75 degrees
Step-by-step explanation:
In ΔDCE,
angle D + angle C + angle E = 180......(sum of the interior angles of a triangle is always 180 degrees)
angle D + 80 + 25 = 180
angle D + 105 = 180
angle D = 180 - 105
angle D (I. e angle CDE ) = 75 degrees
Now, angle CDE and angle FDA are vertically opposite angles, so,
angle CDE = angle FDA..... (vertically opposite angles are congruent to each other)
therefore, angle FDA = 75 degrees
Now, angle CDE and angle BAD are corresponding angles, so,
angle CDE = angle BAD...... ( corresponding angles are congruent to each other)
angle BAD = 75 degrees
Now, angle BAD and angle JAI are vertically opposite angles, so,
angle BAD = angle JAI..... (vertically opposite angles are congruent to each other)
therefore, angle JAI = 75 degrees

The lines of symmetry in a regular polygon are equal to the number of sides minus 2. True or False
Answer:
False
Step-by-step explanation:
A regular polygon may be defined as the polygon that have sides of equal length known as equilateral and angles made up of equal angles, known as equiangular.
The [tex]$\text{number of lines}$[/tex] of symmetry in a regular polygon is always equal to the number of sides of the polygon. For example, a regular pentagon have 5 sides, so the lines of symmetry of the regular pentagon is also 5, a square having 4 sides also has 4 lines of symmetry.
Which linear equation has a slope greater -1 but less than 0?
1. 5x+4y=20
2. 4x+5y=20
3. 5x-4y=20
4. 4x-5y=20
Answer:
2. 4x + 5y = 20
Step-by-step explanation:
Determine the slope of each of the equations;
y = mx + c
where;
m is the slope
In each of the given equations, make y the subject of the formula
1. 5x + 4y = 20
4y = 20 - 5x
y = (20/4) - (5x/4)
y = 5 - 5x/4
m = -5/4
2. 4x + 5y = 20
5y = 20 - 4x
y = 4 - 4x/5
m = -4/5 = -0.8
3. 5x - 4y = 20
4y = 5x - 20
y = 5x/4 - 5
m = 5/4
4. 4x - 5y = 20
5y = 4x - 20
y = 4x/5 - 4
m = 4/5
The question says, which of the slope is greater than - 1 but less than 0
- 1 < m < 0
The only equation with slope greater than -1 but less than 0 is 4x + 5y = 20, with slope -4/5 = -0.8

Answer:
EFG = 104°
GFH = 76°
Step-by-step explanation:
The sum of a linear pair is always equal to 180°
So lets solve for the variable n
2n + 32 + 4n + 16 = 180
6n + 48 = 180
6n = 132
n = 22
So now we know N
EFG = 4n + 16
EFG = 88 + 16
EFG = 104°
GFH = 2n + 32°
GFH = 44 + 32
GFH = 76°

which list of numbers is ordered from least to greatest help pls
Answer: B
Step-by-step explanation:
If you change them all to decimals.
4.8% = .048
1/20 = .05
4.1 x [tex]10^{-1}[/tex] = .41
[tex]\sqrt{4}[/tex] = 2
So, that would be least to greatest.
The sides of a rectangle are in a ratio of 7 : 4. If the perimeter of the rectangle is 176 ft, what is the area of the rectangle? The area of the rectangle is
Answer:
1792
Step-by-step explanation:
The sides of the rectangle is 7 and 4
7x, 4x
2(7x+4x) = 176
14x + 8x= 176
22x= 176
Divide both sides by the coefficient if x which is 22
x= 176/22
x= 8
7x
= 7(8)
= 56
4x
= 4(8)
= 32
Area of the rectangle
= 56×32
= 1792

Answer:
x = 38°
Step-by-step explanation:
Complementary angles = 90°
90° = x + x+14
90° = 2x + 14
104 = 2x
x = 52°
the next angle should be 52 - 14 = 38°
So x = 38°

Answer:
outcomes (top to bottom): SS, SG, GS, GG
all probabilities are 0.25
Step-by-step explanation:
Each outcome is identified by the labels on the ends of the corresponding tree branch, in order left-to-right. The top one is SS, for example, and the next one down is SG. Continuing down the tree, the outcomes are GS and GG.
Each letter has a probability of 1/2, so any pair of letters will have a probability of (1/2)(1/2) = 1/4 = 0.25.
__
This method of identifying outcomes and their probabilities can ensure that you find all outcomes. The sum of probabilities should be 1.00 if the tree is properly constructed.

Caity is 50 inches tall. Caity's brother Michael is 5 inches taller than she is. What is Michael's height in feet and inches?
Answer:
55 inches = 4 feet 7 inches
Step-by-step explanation:
Because Michael is 5 inches taller so 50+5=55, then divided by 12 = 4 remainder 7. So that means Michael is 55 inches tall, or 4 feet and 7 inches

find the measure of angle G
Answer:
135 degrees
Step-by-step explanation:
It is as isosceles trapezoid, so the the base angles are congruent. The sum of the inner angles is 360 degrees
2(4x-7) + 2(11x -8) = 360
8x - 14 + 22x -16 = 360
30x = 390
x = 13
angle F = angle G
angle G = 11 * 13 - 8 = 135 degrees

Answer:
B. 63
Step-by-step explanation:
There are two similar triangles given in the diagram above. Since they area similar, they also have corresponding side lengths that are proportional.
Therefore:
(6 + 3)/3 = x/21
9/3 = x/21
3 = x/21
Cross multiply
21*3 = x
63 = x
x = 63
Please help again I suck at geometry
Answer:
Option (6)
Step-by-step explanation:
By applying sine rule the given triangle XYZ,
sin(X) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
Measure of opposite side (XY) = 12
Measure of Hypotenuse (XZ) = 37
By substituting these values in the given expression,
sin(X) = [tex]\frac{12}{37}[/tex]
Therefore, Option (6) will be the correct option
