Question
The figures are not drawn to scale. Figure 1 shows a rectangular piece of paper RTUW that measures 22 cm by 12 cm. RS = VU = 4 cm. The paper is folded along the dotted line SV such that point T touches point W, as shown in Figure 2.
  1. Find the area of Figure 2. RSVUW, after the folding. 
  2. In Figure 2, ∠RSW is 80°. Find ∠SVU in Figure 2.
