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
