Rob built a sandbox in the shape of a right triangle. If one leg is 5 feet and the other leg is 7 feet, how long is the hypotenuse of the sandbox?

Step-by-step explanation:

use pythagoras’ theorem

square of hypotenuse = square of adjacent + square of opposite

h^2 = 5^2 + 7^2

h^2 = 25 + 49

h^2 = 74

h = square root of 74

h = 8.6 feet

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.

answer: finding the extract measurements and knowing the points
