Question
The figures are not drawn to scale. Figure 1 shows a rectangular piece of paper QSTV that measures 18 cm by 16 cm. QR = UT = 5 cm. The paper is folded along the dotted line RU such that point S touches point V, as shown in Figure 2.
  1. Find the area of Figure 2. QRUTV, after the folding. 
  2. In Figure 2, ∠QRV is 77°. Find ∠RUT in Figure 2.
