Okay you are given the angle 151(given) The equation given a the bottom is equal to the given so you can formulate the equation:
2x+1=151
x=75
Solve for x
The angle adjacent to y are corresponding abgles with the given and if a straight line is equal to 180. So you can subtract 180 from 150 to find y.
151-180=y
y= 29
