Answer:

[tex]x=4, y=8[/tex]

Step-by-step explanation:

step 1

Find the value of y

we know that

In the right triangle of the figure

[tex]cos(30\°)=\frac{4\sqrt{3}}{y}[/tex]

Remember that

[tex]cos(30\°)=\frac{\sqrt{3}}{2}[/tex]

so

[tex]\frac{\sqrt{3}}{2}=\frac{4\sqrt{3}}{y}[/tex]

Simplify

[tex]y=8\ units[/tex]

step 2

Find the value of x

In the right triangle of the figure

[tex]sin(30\°)=\frac{x}{8}[/tex]

Remember that

[tex]sin(30\°)=\frac{1}{2}[/tex]

so

[tex]\frac{1}{2}=\frac{x}{8}[/tex]

[tex]x=4\ units[/tex]
