Question

Can anyone help me in solving question 1 of exercise 6.1

Answer 1

Answer:

Sum of angles on a straight line = 180

AOC + BOE + COE = 180

COE = 110

Sum of angles on a straight line = 180

BOD + BOE + COE = 180

40 + BOE + 110 = 180

BOE = 30

Sum of angles on a straight line = 180

AOD + BOD = 180

AOD = 140

Sum of all angles given = 360

Reflex COE = AOC + BOE + AOD + BOD

Reflex COE = 70 + 140 + 40

Reflex COE = 250
