Pentagons OPQRS and TUVWX are both regular. Find the length of the apothem of TUVWX.

The apothem is the distance from the center of a regular polygon to the midpoint of one side.

Two regular pentagons are always similar, since all the angles are congruent. Not only are their sides proportional, but their heights and apothems will be proportional too.
