What is the angle of elevation of the sun when a 35-ft mast casts a 20-ft shadow Answer by uknouluvme89(30)   (Show Source): You can put this solution on YOUR website!What is the angle of elevation of the sun when a 35-ft mast casts a 20-ft shadow The first thing you would do is make a triangle with the height as 35 ft and the bottom side as 20ft. Let x= the angel of elevation In order to find the angle of elevation, use the trigonometric ratio of tangent. tangent = opposite/adjacent the equation will be: tan x = 35/20 tan^-1(x) = 35/20 x = 60.2551187 degress * I gave you the entire number including all the decimal places because you didn't specify whether or not you needed it rounded. Hope I was of some help!
