A 70°70°
B 110°110°
C 55°55°
D 65°

One side is 55, the other side is 55 as well, the bottom is 180

The answer cannot be determined with the information given. The sum of the angles in a triangle is always 180 degrees, but without knowing the measurements of the other angles of the triangle, we cannot determine the measure of angle z.
