If you could help me with this problem, that would be great:
A surveyor is 980 ft from the base of a fountain. The angle of elevation to the top of the fountain is 29.7 degrees. His angle measuring device is at the same level as the base of the fountain. Find the height of the column of water to the nearest 20 ft.
How do I find this? Please give as much detail as possible & thank you! :)
*Nearest 10 ft. Sorry for the typo(:
