Given that \cos\theta =\frac{16}{65}cosθ= 65
16

and that angle \thetaθ terminates in quadrant \text{IV}IV, then what is the value of \tan\thetatanθ?

Sorry can't answer that question

Hello! i hope this
since the cosine is the ratio of the adjacent side to the hypotenuse, you can see that cos 60° = ½. answer. according to the property of cofunctions (topic 3), sin 30° is equal to cos 60°. sin 30° = ½.
