Answer:

Option D -Parallelogram and rhombus is the correct answer.

Step-by-step explanation:

Option A -Square.

In square all sides are equal and all angles are equal and each angle is equal to 90°

Option B - Parallelogram

In Parallelogram opposites sides are equal and parallel. there is no right angles.

Option C -Rectangle

In rectangle opposites sides are equal and parallel. All angles are equal to 90°

Option D -Parallelogram and rhombus

In Parallelogram opposites sides are equal and parallel. there is no right angles.

In rhombus all sides are equal and parallel. there is no right angles.

Check the picture below

and recall that

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