Question

The leg of a right triangle is 5 units and the hypotenuse is 8 units. What is the length, in units, of the other leg of the triangle?

89 Units

Answer 1

The other leg is equal to 6.24 units.

Explanation:

Using the Pythagorean Theorem:

`a^2 + b^2 = c^2`

However we need to find b:

`c^2-a^2=b^2`

Substitute:

`8^2-5^2=b^2`

`64-25=b^2`

`b^2=39`

Find the square root:

`√(39)=6.24`

The other leg is equal to 6.24 units.
