Answer:
m∠1 = 71°
Step-by-step explanation:
Angle 1 and 2 are complementary, meaning the measures of the two angles add up to 90°.
Set the measures of the two angles equal to 90°

Combine like terms

Solve for x

Plug the value of 'x' back into the given equation for the measure of angle 1

m∠1 = 71°
Im pretty sure the quotient is 92
