Question

the given figure wines a b and CD intersect at O if angle AOC + Angle B equal to 70 degree find angle b o d is equal to 40 degree find angle

Answer 1

please give questions properly.where is your figureand which angle??

Answer 2

$\huge\mathfrak\purple{Answer}$

< AOC = < BOD = 40° ( V. O. A) - - - - - - - (1)

<AOC + <COE + <EOB = 180 ( Linear Pair)

70° + <COE = 180°

<COE = 180 - 170

<COE = 110°

Reflex <COE

= 360 - 110

• = 250°

<AOC + <BOD = 70°

40° + <BOD = 70° ( from equation 1)

<BOA = 70° - 40°

• <BOA = 30°
