In the given figure, O is centre of the circle. Find the value of x and y?

EXPLANATION:

Given figure is a semi-circle.

We know that

The angle in a semi circle is 90°

So the triangle in the semi circle is a right angled triangle

By Pythagoras Theorem

Hypotenuse² = Side²+Side²

⇛x² = 15²+8²

⇛x² = 225+64

⇛x² = 289

⇛x² = 17²

given that

x = 2y

⇛y = x/2

⇛y = 17/2

Answer: Hence, the value of x = 17cm and y = 8.5cm.
