D.41....I think QRS is a right triangle but I can’t see that well. If it’s a right triangle that leaves a 30,60,90 approach.

Answer:

D. 41°

Explanation:


(3x + 9) \degree = 132 \degree \\ (vertical \: \angle s) \\ 3x + 9 = 132 \\ 3x = 132 - 9 \\ 3x = 123 \\ x = (123)/(3) \\ x = 41 \\ \\ \because m\angle QRS =x\degree \\\therefore m\angle QRS = 41\degree
