Lucy drew an isosceles triangle as shown.

A triangle is shown with point Z at the lower left, point Y to the right and slightly up and point X to the upper right. Short line segments cross line segments Y Z and Y X.

If the measure of ∠YZX is 25°, what is the measure of ∠XYZ?

A. 50°
B. 75°
C. 130°
D. 310°

can't tell whether X is the vertex angle or one of the two base angles. Since all of the choices are integers, I'd say 180-(25+25) = 130
