Question

In the figure O and P are the centres of the circles.
angle OAB =60°
a) what is the measure of angle OBA?
b) what is the measure of angle AOB?
c) what is the measure of angle CPD?
d) what is the measure of angle CQD?​

Answer 1

Answer:

The answers are as follows :-

angle OBA = 60° [Angles opposite to equal sides are equal.

angle AOB = 60° [Angle sum property]

angle CPD = 30° [AOB = 2CPD]

angle CQD = 15° [CPD = 2CQD]

This is your answer.

Thank you.
