Question

I need help with the last question about Special Right Triangles

Answer 1

a 45°-45°-90° is a triangle that can be obtained when a triangle has both of its legs with the same length

then, use the pythagorean theorem

`\begin{gathered} x^2+x^2=(\sqrt[]{11})^2 \\ 2x^2=11 \\ x^2=(11)/(2) \\ x=\sqrt[]{(11)/(2)} \\ \text{rationalize} \\ x=\frac{\sqrt[]{22}}{2} \end{gathered}`
