Answer:

The answer to your question is ∠QRT = 47; ∠TRS = 133°

Explanation:

1.- Find the measure of x

The sum of supplementary angles equals 180°

(3x + 5) + (10x - 7) = 180

3x + 5 + 10x - 7 = 180

13x - 2 = 180

13x = 180 + 2

13x = 182

x = 182 / 13

x = 14

2.- Find the value of ∠QRT

∠QRT = 3x + 5

= 3(14) + 5

= 42 + 5

= 47

3.- Find the value of ∠ TRS = 10x -7

= 10(14) - 7

= 140 - 7

= 133°
