The longer base of an isosceles trapezoid measures 22 ft. The nonparallel sides measure 8 ft, and the base angles measure 75°. F

Check the picture below

and recall that

$\bf sin(\theta)=\cfrac{opposite}{hypotenuse}
\qquad
cos(\theta)=\cfrac{adjacent}{hypotenuse}\\\\
-------------------------------\\\\
sin(75^o)=\cfrac{y}{8}\implies 8sin(75^o)=y
\\\\\\
cos(75^o)=\cfrac{x}{8}\implies 8cos(75^o)=x$
