PreCal word math problem help? While traveling across a flat land, you notice a mountain directly in front of you. The angle of elevation to the peak is 2.5º. After you drive 18 miles closer to the mountain, the angle of elevation is 10º. Approximate the height of the mountain.

Errrr... this is not a general help forum.

Besides, this is a classic problem, as our friend would have told you : http://mathcentral.uregina.ca/QQ/databa ... gela2.html . The dimensions are different but the principle is the same.
