Need help with this slope question! Thanks :-)?

Question

A roof rises 2.25 ft over a horizontal distance of 17.37 ft. What is the slope of the roof to the nearest hundredth?

Answer 1

it uses the pythagoras theorem right? horizontal dist. (squared) + height of roof (squared) = slope (squared)

So the numbers you're looking for is the square root of (17.37x17.37) + (2.25x2.25) which is 17.515. (nearest hundredth would be 17.52)

Answer 2

slope = rise/run = 2.25/17.37 =.13

Answer 3

1'.0"  :  7.2 ft. L
