Question

QUESTION--: What should be the angle between the two tangents which is drawn at the end of two radii and are inclined at an angle of 45 degrees?Yar koi to explain kardo please.​

Answer 1

Answer:

The diagram formed is that of quadrilateral.

45+90+90+x=360°

or,x=135°

You will get the image in any proofs related to two tangents from external point to circle are equal. The below diagram is true except one thing. Put 45 degrees to the angle subtended at the centre of circle.

Step-by-step explanation:

Answer 2

$\huge\underline{\overline{\mid{\bold{\pink{ANSWER-}}\mid}}}$

Let PA and PB be the desired tangents to a circle with centre O from an exterior point P

Then,

∠APB = 45°

BOAB must be a cyclic quadrilateral.

∠AOB + ∠APB = 180° = ∠AOB

So, the angle between the two radii must be 135°
