ANSWERS :

HOPE MY ANSWERS HELPS U IF U HAD PLZZZ BRAINLIST MEEEE

Step-by-step explanation:

⇒ △ABC is an equilateral triangle inscribed in a CIRCLE with center O.

⇒ ∠ABC=∠BCA=∠CAB=60o [ Angles of equilateral triangle ]

⇒ We KNOW that, ANGLE SUBTENDED at the center of a circle is DOUBLE angle at any point on circumference of circle.

∴ ∠BOC=2∠CAB

∴ ∠BOC=2×60o

∴ ∠BOC=120o
