Question

If PA and PB are tangents to a circle of radius 5 cm, then their lengths are ……………. cm. 

(A) 5, 13 

(B) 13, 13 

(C) 12, 12

(D) 13, 12

Answer 1

Correct option is: (C) 12, 12

\(\because\) PA & PB are tangents to a circle from outer point P.

\(\therefore\) PA = PB (\(\because\) Tangents from a fixed outer point to circle are of equal length)

Among all given options only option (C) gives two equal length for tangents PA & PB.

\(\therefore\) Option (C) is correct.

Answer 2

Correct option is: (C) 12, 12
