Answer 1

ur trying to solve for x. so using alternate interior angles you know that 2x + x has to equal 180

Answer 2

so i just set it up as 2x+x=180
3x=180 then divide ?

Answer 3

yup assuming that lines l and m are paralell then that is what you would do

Answer 4

okay thank you ;o
so then for this one http://i58.tinypic.com/2e3suhe.jpg
it would be the same ?3x+2x=180?

Answer 5
