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
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

I'm sorry friend
Angle B+Angle D will be 180 not 90
Bcoz sum of Co interior angles is 180 not 90
And thus value of y will be 20 not 10
plz will u reanswer my question
Done that
Check it out
okk
thanks
