Answer 2

Answer:

9 cm

Step-by-step explanation:

PA = PB (Length of tangents drawn from external point are equal)

Therefore, /_PAB = /_PBA = x say

Now In triangle PAB

/_PAB + /_PBA + /_APB = 180

x + x + 60 = 180

2x = 120

x = 60

So triangle PAB is equilateral.

PA = PB = AB

So, AB = 9 cm.
