Question
The figures are not drawn to scale. Figure 1 shows a rectangular piece of paper UWXZ that measures 19 cm by 13 cm. UV = YX = 4 cm. The paper is folded along the dotted line VY such that point W touches point Z, as shown in Figure 2.
  1. Find the area of Figure 2. UVYXZ, after the folding. 
  2. In Figure 2, ∠UVZ is 73°. Find ∠VYX in Figure 2.
