Question

mr. rite wants his roof to be 90degrees at its peak and have a slope of -7/2 on the sunny side of the house. if the height of his roof must be 210, how wide is his house?

Answer 1

Answer:

60 feet

Step-by-step explanation:

The slope of the roof is the vertical distance over the horizontal distance. This means for very 7 feet vertical the roof spreads out 2 feet horizontal. So if the roof is 210 feet vertical, then the horizontal will be _____.

This is found by setting up a proportionand solving for the unknown distance.

$\frac{7}{2}=\frac{210}{y}$

7y = 2*210

7y = 420

y = 60

The horizontal distance will be 60 feet.
