Question

In the given figure O is the centre of the circle determine angle AQB and Angle AMB if BA and PB are tangents

Answer 1

angle AOB = 180-75 = 105

reflex AOB = 360-105 = 255

angle AMB = half of reflex angle AOB [ as we hv done theorem of circle chp]

=1/2 * 255

127.5 degree

angle AQB = half of angle AOB

1/2*105

52.5 degree
