Question

An equilateral triangle ABC is inscribed in a circle with centre. the measure of angle BOC is

Answer 1

We have

∆ ABC is an equilateral triangle

since, each angle is 60°

Now using property angle subtend at the centre of circle is double angle at any point on circumstance of circle

Angle BOC = 2 angle BAC

Angle BOC = 2 × 60°

Angle BOC = 120°

Hence,angle BOC is 120°

Hope it helps you mate ❤️

Answer 2

Answer:

BOC = 120⁰

hope it will help you

angleOBC + BCO + BOC = 180⁰

30⁰+30⁰+BOC = 180⁰

60⁰ +BOC = 180⁰

BOC = 180⁰- 60⁰

BOC = 120⁰
