Answer 1

find the third side using supplementary angles
then recall that the interior angles of a triangle add up to 180

Answer 2

so the answer would be D. 120 then right?

Answer 3

i was torn between c and d

Answer 4

you would be

Answer 5

what is y?

Answer 6

y is 50?

Answer 7

Answer 8

that would be the case if y were 50, but recall that lines are 180 degrees.

Answer 9

so the correct answer isn't here?

Answer 11

can you explain to me how to figure the answer out? i'm confused
