If you make a drawing, you will see that you have created a right triangle with the angle of elevation opposite the leg that is the height of the flagpole.
The length of the shadow is the other leg, adjacent to the angle of elevation.
Applying the trigonometric identity for right triangles:
tan(angle of elevation) = opposite/adjacent -->
tan(15) = height/37 -->
height = 37 * tan(15) = 9.9.
