Find the missing side Lengths (70 POINTS!)

Deffense [45]

Answer:

The sides are as follows: $x=18,\,\,\,y=9\sqrt{3}$

Step-by-step explanation:

Starting with the side y, we can use the tan to solve for y:

$\tan 30^\circ = \frac{9}{y}\implies y = \frac{9}{\tan 30^\circ}={9}\sqrt{3}$

The side x can be determined using sin:

$\sin 30^\circ = \frac{9}{x}\implies x = \frac{9}{\sin 30^\circ}= 18$

So, the sides as as follows: $x=18,\,\,\,y=9\sqrt{3}$

(you can also verify this result is correct using the Pythagorean theorem)
