Jenny wants to know how long the slide is at the playground. She knows the height from the bottom of the ladder to the top of the slide is 6 feet. The bottom of the ladder forms a right angle with the ground. She also measures the distance from the bottom of the ladder to the end of the slide which is 9 feet. What is the length of the slide rounded to the nearest tenth? The slide is approximately ? feet long.
Accepted Solution
A:
the slide is hypotenuse , the ladder and the distance from the ladder to the end of the side are legs, so we can use Pythagorean theorem length of the slide =c, c^2= 9^2+6^2 c^2=81+36=117 √117=10.8 ft
