Assume cos T = .45 and cos W = .89, both T and W are positive, and both T and W determine a terminal point in Quadrant 4. which
emmainna [20.7K]

As both T and W determine terminal points in the fourth quadrant, we know that both angles fall between 270^\circ and 360^\circ. We also know that 0 for 270, and that \cos x is strictly increasing along this interval.

This means that the angle with the larger cosine value must be closer to having a measure of 360 degrees than the angle with the smaller cosine value, so W>T.
