Answer the questions for Angle 𝜃 = −7𝜋/3

Question

a) (4pts) Find the reference angle of 𝜃 = −7𝜋/3

b) (5pts) Find an angle coterminal to 𝜃 = −7𝜋/3 between 0 ≤ 𝜃 < 2𝜋

c) (6pts) Evaluate csc (−7𝜋/3).

Give an exact answer (no decimals).

Answer 1

-7π/3=-7.33° ref=-180-(-7.33)=-172.6666°

Is pi metric 180; or US 3.14?
