1. Use each trig ratio to determine all values of theta, to the nearest degree for
0<=theta<=360.
c)cos=-3/2(no calc)
The cosine ratio is defined as the ratio of the adjacent side to the hypotenuse in a right triangle. Since the cosine ratio cannot be greater than 1, there are no values of theta such that cos(theta) = -3/2.
Therefore, there are no values of theta between 0 and 360 such that cos(theta) = -3/2.
