The formula is A^2+B^2=C^2.
An example of using to solve a problem is below.
Let's say we have a right triangle with a and b given but we are missing c.
A and B are called "Legs" While C is called the Hypotenuse.
A= 12 and B= 16.
Lets solve it.
![\left[\begin{array}{ccc}A^2+B^2=C^2\\12^2+16^2=C^2\\144+256=400\\Now,\;we\;need\;to\;find\;the\;square\;root\;of\;400.\\√(400)= 40\\If\;it\;were\;to\;be\;a\;decimal\;such\;as\;40.162\;we\;would\;round\;to\\the\;nearest\;tenths\;and\;get\;40.2\end{array}\right]](https://img.qammunity.org/2019/formulas/mathematics/high-school/phhk2qsgz19q03ugwt6p76u6xpmo130c1c.png)
Thus, our final answer is 40.
