Given:

RaySTbisects angle RSV

m angle RST =x+ym angle TSV = 2x - 2y

m angle RSV = 64°

Find: x and y

The graph forms adjacent angles.

First, I tried isolating x or y by multiplying 2 (x + y) so I can get 2x + 2y. Then I get 4x = 64?

Not sure. I am completely lost. I don't know whether to combine x + y + 2x - 2y = 64 or substitute.

Please help.

The answers are x = 24 and y = 8.
