Answer:
x = 35
y = 72.5
Explanation:
At your level, it is assumed that those lines are straight. Keeping this in mind, we can find the answer to this problem.
First, we have to find x.
x = 35º because opposite angles are equal (xº is opposite to 35º).
Then, we have to calculate y.
You should know that angles in a straight line add up to 180º.
So: yº + yº + 35º = 180º
You know have to solve this equation (solve for y).
y + y + 35 = 180
y + y = 180 - 35
y + y = 145
2y = 145
y = 145 / 2
y = 72.5
Check: 72.5 + 72.5 + 35 = 180
