Question

This is a math question :

if l parallel to m, angle 1 = 2x+y and angle 4=x+2y and angle 6=3y+20,find angle 7 & 8​

Answer 1

Answer:

angle 7=21x+9y

and angle 8=24/5x+24/5y

Explanation:

1=2x+y implies 2=4x+2y

using the equation we get x=-2/3

and y=7/3

so angle 7=21x+9y

and angle 8=24/5x+24/5y
