Both sides need to equal 180 (The side with the 90 degrees measurement and the side with equations). So first subtract 180 from 90
to get the measurement of 5x and you get 90 but we aren't done yet since we need to find x so now we need to divide 5 by 90
and we get 18 which is X.
Now we need to find the measurement of Y. Now both angles on that side together equals 180 so we need this equation.
First, distribute 5(y + 11)
Then you get this equation :
Now, add the two equations together
and you get this equation
Now subtract 45 from both sides
and divide by 9 on both sides
and you get your answer
So
