Question

in figure 6.13 lines ab and CD interest at O if angle AOC + Angle B equal to 70 degree and Angle B O D equal to 40 degree find angle BOC and reflex angle COD solved​

Answer 1

where is figure 6.13 pls upload photos

Answer 2

$\huge\mathfrak\orange{Answer}$

< 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°
