find the measure of angle A

Answer:
-65
Step-by-step explanation:
8x + 4 = 3x - 6
Bring the 3x over to the 8x and subtract them to get 5x.
5x + 4 = -6
Bring the 4 over and subtract them both to get -10 and then divided 5x with -10 and get -2x.
-2x = 130
Divide -2x with 130 and get -65.
If its wrong I am so sorry!!;( I hope you have a wonderful day<3
