Question

What will be the answer for this ?

Answer 1

Step-by-step explanation:

the measure of an angle subtended by an Arc at a point on the circle is half of the measure of the angle subtended by the arc at the centre

$angle \: apb = 1 \div 2 \: angle \: aob$

angle APB=1/2 angle AOB

angle APB=110/2

angle APB=55°
