Question

PA is tangent drawn from the external point p to a circle with centre o . if poa =65 and A is the point of contact then APO =​

Answer 1

Answer:

since both angles are given the third angle is

angle A+angle O+angle P=180 degree (because of interior angle theorem)

ie 90 degree +65 degree+ angle P=180 degree

155 degree + angle P= 180 degree

angle P = 180-155°

angle P = 25°

therefore angle APO= 25°

angle a was 90 ° because point of contact.
