Question

In the figure below, lines AB and CD intersect at O. If AOC + BOE = 70 and BOD = 40, find (3BOE).

 



Your Answer
A

30

Your Answer
B

60

Correct Answer
C

90

Your Answer
D

180


Solution

The correct option is C

90


AOC + BOE + COE = 180 (Angles on a straight line equals 180)

Given, AOC + BOE = 70

So, COE = 180 - (AOC + COE) = 180 - 70= 110

Again, COE + BOE + BOD = 180 (Angles on a straight line equals 180)
We know that, COE = 110 and BOD = 40

So, BOE = 180 - COE - BOD= 180 - 110 - 40 = 30 
3 × ( BOE) = 90
