In the diagram, PQR is a circle with center O. If ∠OPQ = 48°, find the value of M.
Attached Figure / Diagram
A
96\(^o\)
B
90\(^o\)
C
68\(^o\)
D
42\(^o\)
Verified Correct Answer: A.
Step-by-Step Mathematical Solution
< O\(Q\)P = 48\(^o\) (base angles of isoceles \(\triangle\))
m = 48\(^o\) + 48\(^o\) = 96\(^o\) (exterior angle of a \(\triangle\))
