Here is a sketch of the curve y=cos⁡x∘y = \cos x^\circy=cosx∘ for 0≤x≤3600 \leq x \leq 3600≤x≤360

A graph of the cosine function y = cos x degrees for 0 ≤ x ≤ 360.

Use the graph to find estimates of the solutions, in the interval 0≤x≤3600 \leq x \leq 3600≤x≤360, of the equation:

i.

cos⁡(x)=0.55\cos(x) = 0.55cos(x)=0.55
