What factors do you think are involved in determining the pitch of the roof? Explain your reasoning.

Use the Pythagorean Theorem to solve. This will be a right triangle:

=

Let the slope = the hypotenuse = c

Let one side = a=8

Let the other side = b = 15

Plug-in the values and solve for the c-term

Check you answer by plugging the value of "c" back into the orignial equation and solve.
