When driving west toward the Rocky Mountains, you see a peak 3.0 above the horizon. Your GPS gives your current elevation as 1630 , and according to the map, you're 28.5 (horizontally) from the peak.
Find the peak's elevation

drwls,
What are the units of your 28.5 number? And of your elevation? And the 3.0 ? Is the latter degrees?
You can't do physics without including dimensions with your numbers.
This appears to be basically a trig problem. Use the definition of the tangent of an angle.

Wykeena,
Sorry it is 28.5m horizontally from the peak. You see a peak at 3.0 degrees, and the current eleevation is 1630 meters.

Physics 
drwls,
Elevation (in meters) = 1630 + 28,500 tan 3.0
= 3124 m
