In the given figure, PQR is a triangle in which angle P : angle Q : angle R = 3 : 2 : 1, and PR is perpendicular to RS. What will be the measure of angle TRS?
A. 60°
B. 45°
C. 50°
D. 30°
Answer: Option A
Solution (By Examveda Team)
P : Q : R = 3 : 2 : 13 + 2 + 1 = 6u → 180°
1u → 30°
P = 90° ∠PRS = 90°
Q = 60°
R = 30°
∠P + ∠Q = ∠PRT
90° + 60° = ∠PRS + ∠TRS
150° = 90° + ∠TRS
∠TRS = 60°
