Question

How long is the storage unit This is Pythagorean theorem

Answer 1

Answer:

9 meters

Step-by-step explanation:

We know the hypotenuse is 15 and one leg is 12

a^2 + b^2 = c^2  where c is the hypotenuse and a and b are the legs

12^2 + b^2 = 15^2

144 + b^2 = 225

Subtract 144 from each side

144-144 +b^2 = 225 -144

b^2 = 81

Take the square root of each side

sqrt(b^2) = sqrt(81)

b = 9
