Answer:
<u>8x+12</u>
2
Step-by-step explanation:
(Divide the entire Angle A by 2)
the last equation would be the answer
Add 5x+2x+3x you get 10x bring the 20 down set it equal to 180
you have 10x+20=180
subtract 20 from 180 which gives 160
So now you have 10x=160
divide 10 by both sides you get x=16
