Problema Solution

A children's slide rises 10 feet over a horizontal distance of 9 feet. Find the slope of the slide.

Answer provided by our tutors

use the pythagorean theorem:

a2+b2=c2 where a and b for the right angle (in this case the rise and horizontal distance) and c is the hypotenuse (in this case the slope of the slide)

so a = 10 and b = 9, solve for c

102+92=c2

100+81 = c2

181 = c2

sqrt(181) = c2

simplify this to approximately 13.45 feet
