Question

2. In figure, PA and PB are two tangents drawn from an external point P to a circle with centre C and radius
4 cm. If PA IPB, then the length of each tangent is:
(a) 3 cm
(b) 4 cm
(c) 5 cm
(d) 6 cm
...
ANSWR FAST .......

​

Answer 1

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
