Answer» ∠AOC + ∠BOE = 70°∠AOC + ∠COE + ∠BOE = 180°[ linear PAIR ]So,if ∠AOC + ∠BOE = 70°so,→ 70° + ∠COE = 180°→ ∠COE = 180 - 70→ ∠COE = 110°.∠BOD = ∠AOC [ Vertically Opposite ANGLES ].Now,→ ∠AOC + ∠COE + ∠BOE = 180°→ 40° + 110° + ∠BOE = 180°→ 150° + ∠BOE = 180°→ ∠BOE = 180° - 150°→ ∠BOE = 30°.∠BOD + ∠DOA = 180° [Liner Pair]→ 40° + ∠DOA = 180°→ ∠DOA = 180° - 40°→ ∠DOA = 140°Hence,reflex ANGLE ( ∠COE ) = ∠AOC + ∠DOE + ∠BOD + ∠BOEreflex angle ( ∠COE ) = 40° + 140° + 40° + 30°reflex angle ( ∠COE ) = 250°Step-by-step explanation:PLZ mark as BRAINLIEST ❣️ |
