Question

If figure, PA and PB are tangents such that PA = 9 cm and ∠APB=60°. Find AB​

Answer 1

Answer:

18 root3

Step-by-step explanation:

As PA and PB are tangents and radius is perpendicular to radius and APB = 60 and PA = 9

So APO and BPO are right angled triangle

= tan 30 = 9/x

= 1/root3 = 9/x

= x = 9 root 3

And addition of 9 root 3

becomes = 18 root 3
