Question

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 of the following statements best describes the relationships between t and w?

A. it is not possible to tell from the given information
B. W>T
C. T>W

Answer 1

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<\cos x^\circ<1` for
`270<x<360`, 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`.

Answer 2

Answer:w>t
