Question

Find the length of tangent drawn to a circle with radius 8 cm form a point 17 cm away from the center of the circle

Answer 1

Let O be the center of the given circle.

Let P be a point, such that

OP = 17 cm.

Let OT be the radius, where

OT = 5cm

Join TP, where TP is a tangent.

Now, tangent drawn from an external point is perpendicular to the radius at the point of contact
