Answer:
The answer is in the explaination
Step-by-step explanation:
A + B = 180 degrees
14x - 72 = 180
14x = 108
x = 8
A = 5 times 8 plus 20
A = 60
Answer:
110 degrees.
Step-by-step explanation:
Angle A + Angle B = 180 degrees.
Therefore, 5x+20+9x-92=180
When you solve you get 14x=252 or x=18
When you plug that into A you get 5(18)+20=110
Therefore, A=110 degrees
