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°
