-10.5 = 3.8 cos [2pi/360(x-172)] this is the question and i am trying to solve for x though i don't know that i can break away the x from cos the way i did... is there another way??
i don't think the answer should be negative as the question is looking for a day of the year.
so if i try to solve for x, i end up with
-2.76 = cos [0.017x - 2.924]
-1.8876 = cos 0.017x
-1.8876/0.9999 = x
x = -1.8878
