This is a $30-60-90$ triangle. The variable $x$ is on the hypotenuse, and vis $2$ times longer than the side opposite of $30$:$x=22=4.$ The variable $y$ is opposite of $60($the angle that was not labeled$),$ and is $\sqrt[\phantom{2}]{3}$ times longer than the side opposite of $30$:$y=\sqrt[\phantom{2}]{3}2=2\sqrt[\phantom{2}]{3}.$

Example $2$: $,x=?$

This is a $45-45-90$ triangle because two sides are equal. Therefore, $=45.$ The
