Two angles are supplementary. They have the following measures: m∠QRS=(x+16)° and m∠SRT=(3x)° . What is the measure of ∠SRT ?(1 point)

Answer 1

Since the two angles are supplementary, their measures add up to 180 degrees.

(x + 16) + (3x) = 180

4x + 16 = 180

4x = 164

x = 41

So, the measure of ∠SRT is 3x = 3(41) = 123 degrees. Answer: \boxed{123}.
