In the diagram above, O is the center of the circle and ∠POR = 126^\circ. Find ∠PQR
Attached Figure / Diagram
A
234o
B
117o
C
72o
D
63o
E
54o
Verified Correct Answer: B.
Step-by-Step Mathematical Solution
Reflex < POR = 360^\circ - 126^\circ = 234^\circ
\(\therefore\) < PQR = \(\frac{1}{2} \times 234^\circ\)
= 117^\circ
