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 ? |
23o 26o 29o 19o |
26o |
We have a shortcut, The value of ∠PCB = ∠PCB = \(\frac{90 - ∠APC}{2}\) = \(\frac{90 - 38}{2}\) = \(\frac{52}{2}\) = 26o |
