Question

Find the value of x for which l is parallel to m

Answer 1

For L and M to be parallel, what needs to be the relationship between those angles?

Answer 2

Wait.. What?

Answer 3

They're alternate interior angles.

Answer 4

\[3x+5=180-65\] etc

Answer 5

What does that mean?

Answer 6

Wait, so @satellite73, you have to subtract 180 from 65 and that's the answer? That's easy..

Answer 7

Oh wow. I feel stupid now. Alternate interior angles are congruent.. Duh!

Answer 8

hope it is clear, you get
\[3x+5=115\] and you can solve for \(x\) in two steps
