Question

In the given fig PA and PB are tangents drawn to 'O' centred circle if angle APB =80 then angle AOP = _____





please answer with explanation
​

Answer 1

Step-by-step explanation:

ANGLE FORMED BY QUADRILATERAL IS 360°

SO , OAP + APB + PBO + BOA = 360

LET OAP BE - X

AND TANGENTS FORMED BY A CIRCLE ARE.

90

X + 80 +70+70 = 360

220+X= 360

X = 140
