Question

Find the value of angle AOB​

Answer 1

Theorem 10.8:

The angle subtended by arc at the centre is double than angle subtended by it at any point on the remaining part of the circle.

Explanation:

angle QPR = 35°

angle APB = 35° ( Vertically Opposite Angles )

According to the Theorem 10.8,

angle AOB = 2( angle APB )

angle AOB = 2(35°) = 70°

Answer:

angle AOB = 70°
