Question

Find the length of the tangent CD if AP=3cm and PC=8cm

Answer 1

Step-by-step explanation:

Given,

AP=3cm

PC=8cm

AP=BP (tangents drawn from an external point)

BP=3cm (putting in the values)

now,

PC= BP + BC

8=3+BC (putting in the values)

BC=5cm

BC=CD (tangents drawn from an external point)

CD=5cm.
