IM IN DIRE NEED OF HELP WITH MATH IN IN 8TH GRADE?
Hi I'm in geometry here's my question
the safety rules for a playground state that the height of a slide and the distance from the base of the ladder to the front of the slide must be in a ratio of 3:5 if a slide is about 8 ft long what are the height and distance from the base of the ladder to the front of the slide?
so i know the equasion based on the pythagorean theorem is 8squared=5xsquared+3xsqaured but how to solve??????!!!!!!

This is a right triangle problem
the hypotenuse for a right triangle with sides for 3 and 5 is
c² = 3² + 5²
c² = 36
c = 6
The ratio is then
Corresponding sides of similar triangle have the same prorportion
since 8 = 4/3 * 6
The height is
h = 3 * (4/3)
h = 4 ft <––––
Distance from base to front of ladder
d = 5 * (4/3)
d = 20/3
d = 6 ⅔ ft <–––––
