Answer 1

sum of angle in linear pair always equal to 180 )

∠AOC + ∠COE + ∠BOE = 180°

Given that ∠ AOC + ∠ BOE = 70° plug this value we get

= > 70° + ∠COE = 180°

= > ∠ COE = 180° -70°

= > ∠ COE = 110°

Also

(sum of angle in linear pair always equal to 180° )

∠COE + ∠BOE + ∠BOD = 180°

Put ∠COE = 110° and ∠ BOD = 40° we get

110° + ∠BOE + 40° = 180°

= > ∠BOE = 180° - 110° - 40°

= > ∠BOE = 30
