Answer:
y=30 degrees
x=70 degrees
z= 20 degrees
Step-by-step 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
