Question

Q13. In the given figure, lines AB & CD intersect at O. Find the value of:

a) x

b) ∠

c) ∠

d) ∠​

Answer 1

Answer:

CD is a straight line

Step-by-step explanation:

so angle COE + angle EOB + angle BOD = 180

3x+7+x+5+40=180

12+4x=180-40

12x+4x=140

4x=140-12

4x=128

x=128/4

a) x=32

b) COE = 3x+7 = 3(32)+7 = 96+7 = 103

c) EOB = x+5=32+5=37
