Given: 

Find:  The length of diameter

To find:
The length of diameter
Calculation:
Given,
First we have to find
By the theorem, “An angle inscribed in a semicircle is a right angle”.
Since
It is given that,
Assume that,
Also it is given that,
Then take,
Consider the right angle triangle
Now by Pythagorean theorem,
Consider the right angle triangle
Again by Pythagorean theorem,
Solve the equations (1) and (2)
