Question

o is the centre of the circle AB and AC are tangent drawn to the circle. If angle BAC = 65 degree , then find angle BOC​

Answer 1

Answer:

Given that,

AB and AC are two tangents.

We know that radius make perpendicular to the point of contact.

so, ABOC becomes a quadrilateral.

We know that sum of all angles of a quadrilateral=360⁰

<BAC+ <BOC+<OBA+<OCA=360⁰

65⁰+<BOC+90⁰+90⁰=360⁰

<BOC+245⁰=360⁰

<BOC=360⁰-245⁰

<BOC=115⁰

Answer 2

Answer:

115

Step-by-step explanation:

the image formed will be like this

=> x+90+90+65=360

=> x=360-180-65

=> x=115
