Question

In the figure,O is the centre of the circle.
measure of angle ROQ = 110°.
Find measure of angle QPT.


(1) 55°
(2) 70° (3) 110° (4) 125°
​

Answer 1

Answer:

55degree is the correct answer

The theorem states that the angle subtended by an arc of a circle at centre is double the angle subtended by it at any point on the remaining part of the circle.

Therefore <QPT=110/2=55°

I hope you understood it.

Thank you!
