Question

Assume cos t = .45 and cos w = .89, both t and w are positive values between 0 and 2pi , and both t and w determine a terminal point in quadrant 4. Which of the following statements best describes the relationship between t and w?

A) t>2
B) w>t
C) not eough information
I chose b but I dont understand this question.

Answer 1

cos^-1 0.45 = 63.3°

cos^-1 0.89 = 27.1°

 

The angle for which t is a reference is 296.7°.

The angle for which w is a reference is 332.9°.

 

w > t
