Answer:
B
Step-by-step explanation:
The triangle UVW is similar (or congruent) to the triangle XZY.
U angle of the triangle UVW = 36 degrees
X angle = 180 - 72 - 72 = 36 degrees
Therefore:
V angle = Z angle = 72 degrees
W angle = Y angle = 72 degrees
Triangle UVW is a isosceles triangle at angle U.
=> UV = UW = 5.7 cm
=> the perimeter of triangle UVW = the perimeter of triangle XZY = 5.7 x 2 + 3.7 = 15.1 cm
