What is the correct answer in my question

Question

Solve each equation for exact solutions over the interval [00, 3600].

2sinθ−1=cscθ

Select one:

a.

{300, 2100, 2400, 3000}

b.

{900, 2100, 3300}

c.

{00, 450, 2250}

d.

{300, 2000, 3100}

e.

{150, 1300, 4300}

Answer 1

2 sin θ - 1 = csc θ

2 sin θ - 1 = 1 / sin θ

2 sin² θ - sin θ = 1

Use Algebraic techniques to solve for θ.
