Answer 1

QUESTION:-

In the given Figure, AB and CD are two straight lines intersecting each other at a point O. If COE = 90°,

find the values of x,y,z

EXPLANATION:-

∠COB=180°

So we have,

x+90+2x=180

3x+90=180

3x=90

x=90/3

→x=30

Now,

2x=y

2(30)=y

→y=60°

90+x=z

90+30=z

→z=120°

Therefore,

x=30°,y=60° and z=120° .
