In the 1960s, a fast-food chain called Der Wienerschnitzel had outlets built in a triangular shape. Classify the type of triangle that is used for the front of the building shown in Figure7.47.

Figure 7.47

Suppose my photograph of this building shows the width of the building to be 3.5 in. with the width of the window at the front exactly half of that. If it is known that this window is 9 ft wide, what is the width of the building?
