In Fig. 3, AP and

Answer :

It is given in the question that,

APB = 60o

We know that, tangents drawn from an external point of a circle are equal


Also, we know that angles opposite to equal sides are equal

∴∠ PAB = PBA (i)

Sum of angles of a triangle = 180o

In triangle PAB, PAB + PBA + APB = 180o

PAB + PAB + 60o = 180o

2 PAB = 120o

PAB = 60o

Hence, the sides AB and AP are equal to each other i.e. AB = AP = 5 cm
