Match the trigonometric function with its appropriate approximation. cot 24°

Without using a calculator, compute the sine, cosine, and tangent of by using the reference angle. 4 (Type sqrt(2) for v2 and sqrt(3) for V3.) What is the reference angle? radians. In what quadrant is this angle? (answer 1, 2, 3, or 4) -() - 57 sin cos 4

find an acute angle that satisfies cot theta=1.983

The answer should be in radian form with 2 decimal places.
