AB is a chord of a circle with centre O and P is any point on the circle. If ∠APB = 122°, then what is the measure of ∠OAB ?
Answer & explanation
Correct answer: option 1
From the above given diagram we have
= \(\Theta \) = P - 90
= \(\Theta \) = 122 - 90 = 32
Therefore, \(\Theta \) is \({32}^\circ\).
