Step-by-step explanation:

angle STQ is the supplementary angle (together they are 180° below line MQ) to 2x + 8.

above ST we have a group of 3 angles that combine to 180° :

2x + 8

90°

71 - x

so, to get x first :

2x + 8 + 90 + 71 - x = 180

x + 169 = 180

x = 11

so, the angle MTS =

2x + 8 = 2×11 + 8 = 22 + 8 = 30°.

therefore, the angle STQ is

180 - angle MTS = 180 - 30 = 150°.

These are a pair of angles, adjacent or nonadjacent, whose sum is 90°.

Alexus [3.1K]

A pair of angles, which are either adjacent or non-adjacent, whose sum is 90 degrees, is classified and known as Complementary Angles. Complementary Angles are made from adjacent or non-adjacent angles, when added to together, their sum is equal to 90 degrees.
