Question

Determine the measure of each unknown angle in the diagram below, where lines s and t are parallel.

Answer 1

Just determine which pairs are corresponding and which are supplementary.

Answer 2

I know that
y = 180 - 73
B = 73

But that's all I can figure out

Answer 3

a and B are what?

Answer 4

B is 73 and a is 107 right?

Answer 5

Yep.

Answer 6

So that's all to the question?

Answer 7

Yep.

Answer 8

Thank you!

Answer 9

You are welcome.
Again, with two parallel lines and a transversal, you get 8 angles which relate to each other in only one of two ways.
