Two towers face each other separated by a distance d = 25 m. As seen from the top of the first tower, the angle of depression of the second tower's base is 60o and that of the top is 30o. What is the height (in meters) of the second tower?

Do you know what "angle of depression" means?
Have you been exposed to the 30-60-90 triangle?
