Answer:
The answer to your question is A = 166°
Step-by-step explanation:
Angle A and Angle B are corresponding angles so they measure the same
∠A = ∠B
7x + 40 = 3x + 112
Simplify like terms
7x - 3x = 112 - 40
4x = 72
x = 72/4
x = 18
- Find the value of A
∠A = 7x + 40
∠A = 7(18) + 40
∠A = 126 + 40
∠A = 166°
