Answer:
x = 19
y = 23
Step-by-step explanation:
1. Find the value of x, so we do (5x+20) + (4x-11) = 180 because of the supplementary theory.
2. We should get 19 for x, then we find the angle measurement for the most bottom left angle.
3. You should get 65 degrees for that angle. We also now know that the corresponding angle has the same angle measurement of 65 degrees.
4. Solve for y like this: 2y +19 = 65, you should get 23 for y.
