Answer:

y=30 degrees

x=70 degrees

z= 20 degrees

Explanation:

so, a triangles interior angles add up to 180 degrees.

so then y= 180-110-40 = 30

then x is on a strait line with 110 degrees so they should add up to 180 degrees.

so then x=180-110=70 degrees

Last, z is in the same triangle as the right angle, which is equal to 90 degrees and x which is equal to 70 degrees.

so then z=180-70-90=20 degrees
