Question

two tangents PA and PB to a circle with centre O are inclined to each other at an angle of 70°.Then how much is angle OAB?​

Answer 1

Answer:

ANSWER -->>35°

Step-by-step explanation:

Give -> angle APB = 70°

angle APO= ½ angle APB

½× 70

Ans---(35°)

if wanted to find ↓↓↓↓

finding the angle AOP

angle PAD=90°

therefore ∆ OAP

angle OAP + angle APO + angle POA = 180°

angel= 180- 35-90

{{{angle AOP = 55° }}}

ANSWER

_-_----______---______---_& BYE

Answer 2

Answer:

angle APB =70

angle APO =HALF OF ANGLE APB

=HALF INTO 70

=35
