Question

From an external point p, tangents pa and pb are drawn to a circle. Tangent is drawn at point e which intersects pa and pb at c and d respectively. If pa = 15 cm, the perimeter of triangle pcd, in cm

Answer 1

Step-by-step explanation:

Given : PA and PB are tangent to the circle with centre O. CD is a tangent to the circle at E which intersects PA and PB in C and D respectively and PA = 14 cm. Lengths of tangents drawn from as external point to a circle are equal. = 14 cm + 14 cm = 28 cm.
