The Pythagorean's Theorem
The lengths of the three sides of a right triangle can be related by the Pythagorean formula as follows:
![c^2=a^2+b^2](https://img.qammunity.org/2023/formulas/mathematics/high-school/udh1dsx7kwgfauditnn86pp2qhoycm1tvv.png)
Where c is the hypotenuse and a and b are the legs of the triangle.
The figure shows a right triangle where both legs are given as a = 6 ft and b = 12 ft. Applying the formula:
![\begin{gathered} c^2=6^2+12^2 \\ c^2=36+144 \\ c=\sqrt[]{180} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/ome41gd5ay5a3bov7odnrfgjfbaqf808qs.png)
Approximating to the nearest thousandth:
c = 13.416 ft
