And this one plsssesse need help can't fail​

Answer 1

`\begin{array}{llll} \textit{using the pythagorean theorem} \\\\ a^2+o^2=c^2\implies a=√(c^2 - o^2) \end{array} \qquad \begin{cases} c=\stackrel{hypotenuse}{13}\\ a=adjacent\\ o=\stackrel{opposite}{5} \end{cases} \\\\\\ a=√( 13^2 - 5^2)\implies a=√( 169 - 25 ) \implies a=√( 144 )\implies a=12`
