Question

in the given figure if angle aob is equals to 80 degree then angle APB is equal to dash​

Answer 1

Answer:

40 degree

Step-by-step explanation:

since the angle sustended at the centre is double the angle sustended by the two chords therefore,angle AON=2angle APB hence ,80 degree=2angleAPB and thus, angle APB is 40 degree

Answer 2

since the angle sustended at the centre is double the angle sustended by the two chords therefore,angle AON=2angle APB hence ,80 degree=2angleAPB and thus, angle APB is 40 degree.
