Answer:
Angle VYZ = 27 degrees
A rhombus has 4 equal sides.
That makes Triangle VWX an isosceles triangle.
That means, Angle WXV is also 63 degrees.
All the angles in a triangle add up to 180 degrees:
63 + 63 + x = 180
126 + x = 180
x = 54 degrees
The angle opposite of Angle VWX (Angle VYX) also equals 54 degrees.
That means Angle VYZ = 1/2 of 54 = 27
Angle VYZ = 27 degrees
