Pls someone help me with this

Answer 1

Check the picture below.

`\begin{array}{llll} \textit{using the pythagorean theorem} \\\\ c^2=a^2+o^2\implies c=√(a^2 + o^2) \end{array} \qquad \begin{cases} c=\stackrel{hypotenuse}{AB}\\ a=\stackrel{adjacent}{6}\\ o=\stackrel{opposite}{6} \end{cases} \\\\\\ AB=√( 6^2 + 6^2)\implies AB=√( 36 + 36 ) \implies AB=√( 72 )\implies AB=6√(2)`
