The hypotenuse of a right triangle is 5 feet. One leg of the triangle is 3 feet. What is the length of the other leg (rounded to the nearest hundredth) ?

4 feet

Step-by-step explanation:

The formula to solve for the hypotenuse is

hyp^2 = side^2+side^2

But in this question, we don't have to solve for the hypotenuse so we do the opposite. Let's name the given side, side a and the other side, side b

With the given hypotenuse and one side we use this formula:

side^2=hyp^-side^2

Hypotense = 5 feet

Side b = hyp^2-side^2

Side b = 5^2 - 3^2

Side b = 25 - 9

Side b = 16

Side b = sqrt of 16

B = 4 feet

Therefore B = 4 feet
