arctan (107/90) =?
very difficult to do without a diagram ill try ||||_____ duck vertical lines are slated, 107 horizontal meterde is shaded, 90 voeten. Gebruik trig to determine the angle at “a” if you driehoekjetan a = OPP / adjtan a = 107 / 90a = tan-1 (107/90)
Suppose that x is the angle of the sun tan x = x 107/90tan = 1.18 x = 49.93 degrees
