    number 1 is wrong.. <1 and <2 are supplementary...but they're not congruent

    remember the transversal law.. |dw:1349494407179:dw| the angles with one line are congruent to the angles with one line...angles with two lines are congruent to angles with two lines

    as for number 2..you can figure it out by looking at <1 and <8...if you notice, they are both OUTSIDE and on DIFFERENT SIDES do those capitalized words give you any hint?

    supplementary angles means that if you add 4x and x + 30 you get 180

  27. lgbasallote Group Title

    so add 4x and x + 30 and set it equal to 180 then solve for x

    okay so wouldn't add 5 to 30 or times 30 by 5? hope that makes sense.

    would a way to solve the problem be by taking 30 away frm 180 then dividing by that number by 5?

    it seems 1 is the supplement of x + 30 so you have to subtract 60 from 180
