Question

an equilateral triangle ABC is inscribed in a circle which centre o. the measure of the angle BOC is​

Answer 1

Answer:

60°

Step-by-step explanation:

In an. equilateral triangle all angles are equal and sum of angles is equal to 180°

BOC+OCB+CBO=180°

3(BOC)=180°

BOC=180°/3

BOC=60°

Answer 2

Answer:

120°

step by step solution:

ABC is an equilateral triangle so the angle BAC=60°

angle made by a chord on centre is double the angle made by the same chord on the circle

angle BOC = 2 angle BAC

= 2×60°

= 120°
