Question

A circle with diameter AC is intersected by a secant at points B and D. The secant and the diameter CA produced intersect at point P outside the circle. AE and CF are perpendiculars drawn from the extremities of the diameter CA to the secant. If EB = 4 and BD = 12, then find DF.

Answer 1
