Answer:
x = 60
y = 120
z = 60
Step-by-step explanation:
For a triangle with all equal sides, the inside angles will all be 60 degrees
To find x, since it is the opposite side of a 60 degree angle,
it will be 60 itself
for y, a line is technically 180 degrees, so you can find it by doing:
180 - 60(which is the inside angle right next to it) = 120
For z, this is actually a trick where it is also an equilateral triangle (all sides are the same)
So for z, since it is an equilateral triangle, will have an angle of
60
