Question

In a right triangle, a and b are the lengths of the legs and c is the length of the hypotenuse.

If a = 6.7 feet and c = 10 feet, what is b? If necessary, round to the nearest tenth.

Answer 1

7.4

Explanation:

Use Pythagorean Theorem:
`a^2+b^2+c^2`

In this case we have a and c. So let's plug those into the equation:

`(6.7)^2+b^2=10^2`

`44.9+b^2=100`

`b=√(55.1)`

`b=7.4`
