. Given that O is the centre of the following circle, find the values of the unknowns.​

Given:

Radius of circle is 13 cm

Height of triangle is 5 cm

To find:

Value of 'a' and 'b'

Steps:

To find value of 'a', we will use Pythagoras theorem as the triangle is a right angle triangle,

A² + B² = C²

Now to find the value of 'b', i will use law of cosine,

Therefore, the values of 'a' and 'b' is 12 and 67.38 respectively
