so find the 180 degrees in the line on the top. that should mean that u need to do 61+57=118. then do 180-118=62. so if y=62, then you have to do another 180 degrees inside the triangle. u would have to do the answer for y, 62, and add 62 with 67. then u would get 129. do 180-129=51. the answer for x is 51.
