Answers: a = III, b=positive, c= π/6, d=C, e=√3

a)
(19\pi)/(6) - (12\pi)/(6) = (7\pi)/(6) which is located in Quadrant III.

b) cos is negative and sin is negative so cot (cos/sin) is positive.

c)
(7\pi)/(6) - \pi = (\pi)/(6)

d) cot(π/6)

e) cot =
(cos)/(sin) =
(-√(3) )/(-1) = √(3)

Answers: BC =
√(17), AC =
2√(17),

30°-60°-90° triangle has corresponding sides of: b - b√3 - 2b

AB = b√3

AB = √51

⇒ b√3 = √51

⇒ b = √17

BC = b

⇒ BC = √17

AC = 2b

⇒ AC = 2√17
