In the diagram, RT is a tangent to the circle at R, < PQR = 70\(^o\), < QRT = 52\(^o\), < QSR and < PRQ = x. Calculate the value of x.
Attached Figure / Diagram
A
70\(^o\)
B
58\(^o\)
C
55\(^o\)
D
48\(^o\)
Verified Correct Answer: B.
Step-by-Step Mathematical Solution
x = 180\(^o\) - (52\(^o\) + 70\(^o\))
= 180\(o\) - 122\(^o\)
= 58\(^o\)
