Question

In fig Pa and pb are two tangent drawn from an external point p to a circle with certre point c and radius 4 cm if pa and pb then the length of each tangent is

Answer 1

CA is perpendicular to AP and CB is perpendicular to BP

Again AC = BC = 4 (radius of the circle)

Also AP = PB = (Tangents from point P)

So, BPAC is a square.

=> AP = PB = BC = CA = 4 cm

So, length of tangents are 4 cm each

Answer 2

CA perpendicular AP and CB perpendicular BP

AC =BC=4(radius of circle)

Also, AP = PB( tangents from point P)

So, BPAC is a square.

AP=PB=BC=CA=4cm

So, the lengths of tangents are 4cm each

Hope this answer helps you.
