Answer:

x=9,\\y=9\sqrt{3}

Step-by-step explanation:

Using trig for right triangles:

\sin 30^{\circ}=\frac{x}{18},\\x=18\sin 30^{\circ}=\boxed{9},

\cos 30^{\circ}=\frac{y}{18},\\y=18\cos 30^{\circ}=18\cdot\frac{\sqrt{3}}{2}=\boxed{9\sqrt{3}}.

If you aren't familiar with trig, this may have been introduced to you as a special triangle. In that case, the ratios of the sides of a 30-60-90 triangle are always:

x:x\sqrt{3}:2x, where 2x is the hypotenuse and x is always the side opposite to the 30^{\circ} angle
