Circle centre O with points A, B and C on it; angle ACB = 76°; tangents PA and PB meet at P outside the circle; radii OA and OB drawn

Diagram NOT accurately drawn

\(A\), \(B\) and \(C\) are points on a circle, centre \(O\).
Angle \(ACB\) = 76°
\(PA\) and \(PB\) are tangents to the circle.

Calculate the size of angle \(APB\).
