Question

Find the missing side length

Answer 1

\[28^{2}+35^{2}=c ^{2}\]

Answer 2

I know its 784+1225=2009
But how do I put it back in that form?

Answer 3

This is how we would write it...

Answer 4

\[\begin{array}{cc}
28^{2}+35^{2}&=&c ^{2}\\
784+1225&=&c ^{2}\\
2009&=&c ^{2}\\
\sqrt{2009}&=&|c|
\end{array}
\]

Answer 5

Since we know the length of a side will be positive, then \(|c|=c\).

Answer 6

Thank you.
