AB is a diameter of a circle with centre O. The tangent at a point C on the circle AB, when produced, meet at the point P. If ∠APC = 38o, then what is the measure of ∠PCB ?
Answer & explanation
Correct answer: option 2
We have a shortcut,
The value of ∠PCB =
∠PCB = \(\frac{90 - ∠APC}{2}\)
= \(\frac{90 - 38}{2}\)
= \(\frac{52}{2}\) = 26o
