1. the cosine is positive in quadrants I and IV
so cos 58° = cos(360-58)°
= cos 302°

3. The cosine is positive in Quadrants I and IV, so;
cos 58 = cos(360-58)
= cos 302
The angle that has the same cosine as angle 58 is 302. You can check this using your calculator.
cos(58) = 0.5299192642
cos(302) = 0.5299192642
