Question

Find the measure of the numbered angle.
m∠7 =

Answer 1

Explanation:

∠7 = 180 - 90

∠7 = 90°

see image below

Answer 2

90°

Explanation:

angle 7 is supplementary to the angle next to itself which has a measurement of 90° and since the sum of two supplementary angle would be 180° we can say that m<7 = 90° as well
