Answer
$x_1=48.50~cm$
$y_1=28~cm$
$x_2=28~cm$
$y_2=48.50~cm$
Work Step by Step
$cos~30°=\frac{x_1}{56}$
$x_1=56~\frac{\sqrt 3}{2}=48.50~cm$
$sin~30°=\frac{y_1}{56}$
$y_1=56~\frac{1}{2}=28~cm$
$cos(30°+30°)=cos~60°=\frac{x_2}{56}$
$x_2=56~\frac{1}{2}=28~cm$
$sin(30°+30°)=sin~60°=\frac{y_2}{56}$
$y_2=56~\frac{\sqrt 3}{2}=48.50~cm$
