MARK AS BRAINLIEST

length of tangents from external point to a circle are equal.

It is given that , from point P  on the common tangent of two circles touching each other externally,tangents PA and PB are drawn to the circles.

Also, PA= 5 cm

PA= PM= 5 cm→→[ length of tangents from external point to a circle are equal.]------(1)

PM= PB= 5 cm→→[ length of tangents from external point to a circle are equal.]--------(2)

Equating (1) and (2)

So, Length of tangent PB= Length of tangent PA=5 cm
