The height of the object and the length of the shadow are proportional, so:

The length of the flagpole shadow divided by the length of Maria's shadow is equal to the height of the flagpole divided by Maria's height.

So just solve for x. Hint: Cross-multiply and then divide by the coefficient on x.
