Answer:
m∠B = 31°
Step-by-step explanation:
First, find the measure of angle ACB by subtracting its supplement from 180 degrees:
180 - 113 = 77
m∠ACB = 77°
Then subtract both m∠A and m∠ACB from 180 degrees, since the interior angles of a triangle always add to 180°:
m∠B = 180° - 72° - 77°
m∠B = 31°
X = -1162.5
Subtract 2,401 from both sides.
0 = 76 - 2401 - 2x
0 = -2325 - 2x
Add 2x on both sides.
2x = -2325
Divide both sides by 2.
x = -2325 / 2
x = -1162.5
There is the answer.
