Step-by-step explanation:

$\frac{y}{20 \sqrt{3} } = \sin(30)$

$y = 20 \sqrt{3} \times \frac{1}{2}$

$y = 10 \sqrt{3}$

$\frac{x}{20 \sqrt{3} } = \cos(30)$

$x = 20 \sqrt{3} \times \frac{ \sqrt{3} }{2}$

$x = 30$

option D, x=30 and y = 10√3

The whole set its self costs $159.

25% is being subtracted from $159.

To find the sales price just use your phone calculator or any calculator to subtract 25% from 159.

The sales price is $119.25.
