Y is 88 degrees because on the other side is 92 degrees. A straight line is 180 degrees. 88+92=180. Now that you have 88 and 50, add them together to get 138 degrees. Subtract 130 from 180 to find the missing value of x. 180-130=50. X=50 degrees
Since a straight line is 180 degrees so subtract 92 to find y Y=180-92=82 And the sum of all angles of a triangle = 180 degrees so just put it all in an equation for x 180=82+x 98=x
