    alright well if you just look at the link i gave u u will definitely get the answer : alternate exterior angles exterior means outside of two parallel lines so alternate exterior angles opposite side of transversal lines |dw:1443299612783:dw| in this example b and c are alternate exterior angles and alternate exterior are equal so you can write b=c

    well a linear pair are supplementary why would they be looking for linear pair or supplementary? they already said 3 and 4 are both of those.. it just seems repetitive to say is again but that is true <3+<4=180 since the angles <3 and <4 are supplementary and they are supplementary for the reason that they are a linear pair

    we have to prove that angle 3 equal 70 so if if angle 4 and 3 are supplementary and the given is angle 4 =110 110 + angle 3 =180 solve for angle 3 you will get 70 so i'm pretty sure it's okay to repeat the same definition for C and D right or not >>
