Answer:

  4. b =-√(3)/3

  5. 1/2

Step-by-step explanation:

4. The tangent is negative in the second quadrant. The sine value tells you the reference angle is 30°, so the actual angle is 150°. The corresponding tangent is ...

  tan(150°) = -(√3)/3

__

5. The cotangent is the inverse of the tangent, and vice versa.

  tan = 1/cot

  tan(θ) = 1/2
