Answer:
Step-by-step explanation:
∠QRT is supplementary to ∠SRT - meaning the sum of their angles equals 180°.
If ∠SRT = 110°, you can subtract 110 from 180 and find
that the measure of ∠QRT = 70°.
180 - 110 = 70°
The interior angles of a triangle add up to 180.
Add the two angles you have - ∠TQR and ∠QRT
74 + 70 = 144
Subtract from 180 - 144 = 36°
so ∠QTR = 36°
