Question

Find the length of the tangent from a point M which is at a distance of 17 cm from the centre O of the circle of radius 8 cm​

Answer 1

Answer:

15 cm would be your answer.

Step-by-step explanation:

Let the length of tangent be l

and we know that the angle between radius and tangent through the point of contact is 90°

So, by Pythagoras theorem

l sq. +r sq.=t sq. {r is length of radii and t is the length between center and point from which tangent is drawn}

l sq.= t sq.- r sq.

l sq.= 17×17-8×8

l sq.=289-64

l sq.= 225

l= 15 cm
