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°
