Answer:

Step-by-step explanation:
is in the fourth quadrant
Where sin and tan are < 0 , cos > 0
The related acute angle is 2π - =
Hence
sin([ ) = - sin(
) = -
= -
cos() = cos(
) =
tan(= - tan(
= - 1
The tangent meets the radius at a right angle.
We use (the converse of) the Pythagorean Theorem to check:
Not a right triangle
