Question

Tangents from outside point P to a circle with Centre o r p a and P V were angle aob is 80 then angle APB is tangents from an outside point P to a circle with Centre O and P A and P B were angle A B equal to 80 degree then angle APB is

Answer 1

Answer: 100°

Step-by-step explanation: Radius is perpendicular to t tangent at t point of contact.

<OAP=<OBP=90°

In quadrilateral OAPB all angles are 360°.

By angle sum property, <APB=100°
