TEST YOUR UNDERSTANDING | FOR EXAMPLE 5.12

Find a formula for the roof line in the example if the center height is $8\text{feet}$ above the outside wall rather than $4\text{feet}$.

EXAMPLE 5.12 ROOF LINES

The outside wall of a house is $10\text{feet}$ high. From the western wall, the roof rises $4\text{feet}$ over a horizontal span of $16\text{feet}$ and then descends at the same rate another horizontal span of $16\text{feet}$ to the eastern wall (see Figure 5.55)
