Answer:

  5 in

Step-by-step explanation:

The figure's angles are presumed to be right angles everywhere, so the left-side vertical dimension is equal to the right-side vertical dimension.

The right side is marked as 15 inches.

The left side has two vertical segments, one of which is 10 inches. Since the total left-side height must be the same as the right-side height, we have ...

  10 in + ? = 15 in

  ? = 5 in . . . . . . subtract 10 in

The missing height is 5 inches.
