Question

In the figure given below, PA is 12 cm in length,
AB is 8 cm in length is a chord of the circle
with centre O and PQ is the tangent. Find the
length of the tangent PQ.
​

Answer 1

Step-by-step explanation:

PB=12Cm - 8Cm = 4cm

By using tangent secant theorem we get:

PQ^2=PB×AP

PQ^2= (12-8)×12

PQ^2 = 4×12

PQ = 4root3
