In the diagram, RT is a tangent to the circle at R, < PQR = 70\(^o\), < QRT = 52\(^o\), < QSR and < PRQ = x. Find the value of y.
Attached Figure / Diagram
A
70\(^o\)
B
60\(^o\)
C
52\(^o\)
D
18\(^o\)
Verified Correct Answer: C.
Step-by-Step Mathematical Solution
∠QRT = ∠SRT = 52 (opposite angles)
∠SRT = y = 52 (alternate angles)
y = 52\(^o\)
