Answer:
17°
Explanation:
See the picture :)
We know these triangles are congruent, so angle ZWY = XWY. 60° ÷ 2 = 30°, and this allows us to find the third side of trangle WXY. Traingles have 180°, so we subtract the known angles 133° and 30° from that to get 17°. This is the measure of angle XYW. However, since the triangles are congruent, this is also the measure of angle ZWY.
