Question

Find the missing side of the triangle. Side c is the hypotenuse and sides a & b are legs.

a = 6.3. mi, c = 15.4 mi

Answer 1

`b=14.0524019299`

Explanation:

Use the Pythagorean theorem to solve:
`a^2+b^2=c^2`

`(6.3)^2+b^2=(15.4)^2` <-- plug in a and c values into equation

`39.69+b^2=237.16` <-- take out parentheses

`b^2=197.47` <-- subtract 39.69 from both sides

`b=14.0524019299` <-- take the square root of 197.47

Not sure how much you want to round to so that's the exact answer.

Answer 2

14.05 is as close as I got

Explanation:

6.3 squared + b squared = 15.4 squared
