Question

Pa and pb are two tangents drawn from an external point p to a circle with centre c and radius 4 cm of pa perpendicular to pb than the length of each tangent is

Answer 1

Answer:CAPB will be a square

CA=AP= PB = BC=4 cm

Length of tangent = 4 cm

Answer 2

Answer:

PA  and PB both are 4 cm

Step-by-step explanation:

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
