5 cos θ = 3

cos θ = 3/5

arccos 3/5 = θ

θ = 53.13 degrees

 

if the answer should be in radians, you can simply follow my steps but use the radians instead (for calculator use)

nice answer, just note that the question asks for the entire solution set, which is 360n±51.13, where n is an integer.
