Answer:
R = 101
S = 131
Step-by-step explanation:
First, you will want to get your angle T. Since T is on the same line as the angle with 128 degree, you can easily find angel T. They are supplementary angels and form 180.
T=180-128
T=52
You also know that all angles in a triangle equal to 180
Use that to find angle S
180 = R+S+T
180 = 79 + S + 52
180 - 79 - 52 = S
49 = S, exterior S = 180-49 = 131
Exterior R = 180 - 79 = 101
Now add all your exteriors
Answer:
88
Step-by-step explanation:
44 / 0.5 = 44*2 = 88
Answer:
Multiply the w x h x l
Step-by-step explanation:
Answer:
m < 1 = 18°
Step-by-step explanation:
If <ABD = 72°, and m < 2 is three times the measure of m < 1, then:
Let < ABC = m < 1 = x
< CBD = m < 2 = 3x
We can set up the following formula, since the sum of the measures of angles < 1 and < 2 is equal to <ABD (72°):
m < 1 + m < 2 = < ABD
x + 3x = 72°
Add like terms:
4x = 72°
Divide both sides by 4 to solve for x:

x = 18
Since x = 18, and m < 1 = x , then m < 1 = 18°.
And since m < 2 = 3x, then m < 2 = 3(18°) = 54°.
Let's check to see whether we derived the correct answers by plugging in the values of m < 1 and m < 2 into the established formula:
m < 1 + m < 2 = < ABD
18° + 54° = 72°
72° = 72° (True statement).
