From an outside point P, two tantents, PA and PB, are drawn to a circle. Given that the length of PA is 12 cm, what is the length of PB?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 12 cm.
The lengths of two tangents drawn from a single external point to a circle are always equal.
Tangents PA and PB are from an external point P to the circle.
So, PA = PB = 12 cm
