On a mountain bike trip along the Gemini Bridges Trail in Moab, Utah, Niko stopped on the canyon floor to get a good view of the twin sandstone bridges. Niko is standing about 60 meters from the base of the canyon cliff, and the natural arch bridges are about 100 meters up the canyon wall. If his line of sight (diagonal line) is 5 meters above the ground, what is the angle of elevation to the top of the bridges? Round to the nearest thousandth degree.
