Answer:

137°

Explanation:

So, both are equal to each other due to them being the same degree angle.

5x + 7 = 8x - 71

subtract 5x on both sides

7 = 3x - 71

add 71 to both sides

7 + 71 = 3x - 71 + 71

78=3x

divide both sides by 3

78/3 = x

x = 26

insert x into the equations

5(26)+7°

= 137°

8(26)-71°

= 37°
