Question

HELP...PLEASEEEE!!!!! I put the question in an attachment.

Answer 1

Fist selection offered as an answer.

Answer 2

how did you get that?

Answer 3

Because the parallelogram in divided in half, we know that the triangles are the same (like if you were to do the same with a square) So then every angle one one triangle is the same on the other.
Remember that all the angles of a triangle will add up to 180 degrees, no matter what. So for the top triangle we already have two, just add them together (21+103) to get 124. Now take 124 and subtract that from 180 (180-124=56) and there you go, we have completed triangle one, and found y.
And since both triangles are the same, the angles are the same. So x=103, same as the top. Then just do the same thing we did to find all the angles of the top triangle, add the angles together, subtract it from 180 and you have your answer (56+103=159)... subract from 180 (180-159=21) and there you go, we have them all.
x=21, y=56, z=103

Answer 4

x=21 degrees, alternate angles are equal.
y=180-103-21=56 degrees
z=103, corresponding congruent triangle angles are equal.

thanks that helped me a lot!
