Question

In the figure if ab||cd then what is the value of y

Answer 1

Answer:

i think you want this - Given:Angle D=5y

Now,

Angle B=y+2y+y

Thus, Angle B=4y

Now,

Angle B +Angle D=180 (Co-Interior Angles

Put Value of angle b and angle d as obtained above in this equation

4y+5y=180

9y=180

y=180/9

y=20
