Question

Which of the following shows the length of the third side, in inches, of the triangle below?

Answer 1

`\bf \textit{using the pythagorean theorem} \\\\ c^2=a^2+b^2\implies √(c^2-b^2)=a \qquad \begin{cases} c=\stackrel{hypotenuse}{61}\\ a=adjacent\\ b=\stackrel{opposite}{11}\\ \end{cases} \\\\\\ √(61^1-11^2)=a\implies \implies √(3600)=a\implies 60=a`
