To Find :The distance JK in terms of a, b and c.

Answer to Problem 29WE
The JK in terms of the a, b and c is
Explanation of Solution
Given information:
Consider a right angled
Here the
Also,
Side AB is tangent to the circle.
As the circle is tangent to AB . Then the inscribed angle will be half of centered angle. So, the centered angle will be:
Draw a line from C perpendicular to AB .
In triangle ABC and AHC , angle A is common and other angle is right angled.
Therefore, they are similar.
Further, CH and JK both is radius.
