Took a bike ride and traveled 1.66 miles (8765 ft) and increased in elevation 156 ft. How do I calculate the angle of acent?
---------------------
Draw the picture: a right triangle with 8765 ft base and 156 ft opposite
the angle of ascent (A).
--------
tan(A) = 156/8765
A = tan^-1(156/8765)
A = 1.02 degrees
