Question

PQ is a tangent to a circle with Centre O if angle a b is equal to 30 degree find angle abp and Angle A o b ​

Answer 1

angle a b is equal to 30 degree .

recheck the question.

Answer 2

angle ABP=60°

because every tangent makes 90°angle with radius

OBP+ABP=90°

30+ABP=90°

ABP=60°

angle AOB=120°

because

sum of all angles of triangle is equal to the 180°

OAB+AOB+OBA=180°

30°+AOB+30°=180°

AOB+60°=180

AOB=180°-60°

AOB=120°
