Question

The length of one leg of a right triangle is 24 ft, and the length of the hypotenuse is 40 ft.

What is the length of the other leg?



64.0 feet

46.7 feet

32.0 feet

6.3 feet

Answer 1

First set up your formula. A squared plus b squared equals c squared. C squared is the hypotenuse. Set it up like this;

24 squared plus b squared equals 40 squared.

576 plus b squared equals 1600

B squared equals 1600 - 576

B squared equals 1024

Then you square root it

The answer is 32.

Answer 2

h^2=x^2+y^2

y^2=h^2-x^2

y^2=40^2-24^2

y^2=1024

y=√1024

y=32 ft
