Answer:
29/3 = x
Explanation:
Well it’s a 90° angle and it’s separated into two parts, one of which is 56°. To find the other part, you subtract 56 from 90. You should get 34°. Then you set 3x+7 equal to 36°:
3x + 7 = 36
Subtract 7 from both sides:
3x = 29
Divide both sides by 3:
29/3 = x
you cannot simplify this anymore so that is your final answer
