In the diagram, O is the center of the circle. \(\overline{PQ}\) and \(\overline{RS}\) are tangents to the circle. Find the value of (M + N).
Attached Figure / Diagram
A
120\(^o\)
B
90\(^o\)
C
75\(^o\)
D
60\(^o\)
Verified Correct Answer: B.
Step-by-Step Mathematical Solution
m + n + 90\(^o\) + 180\(^o\) (sum of angle in a \(\triangle\))
m + n = 180\(^o\) - 90\(^o\)
m + n =90\(^o\)
