Answer:
x = 12.5 degree
y = 220 degree
Explanation:
The 1/2y is equal to the 110-degree angles, so to find the y, we take
110 times 2 = 220. So, the answer for y is 220.
The (4x + 20) and 1/2y must add up to 180 degrees. We know one is 110 degrees, so the (4x + 20) must be equal to 70 degrees.
4x + 20 = 70
4x = 50
x = 12.5 degree
So, x = 12.5 degrees and y = 220 degrees.
