Answer:

Step-by-step explanation:
We want to solve the equation:

In the interval [0, 2π).
Notice that this is in quadratic form. Namely, by letting u = sin(θ), we acquire:

Factor:

By the Zero Product Property:

Solve for each case:

Back-substitute:

Use the Unit Circle. Hence, our three solutions in the interval [0, 2π) are:

Answer:
the equation in letter D is a linear function.
This isnt something I can do... But draw and label a tape diagram that goes from 0 to 30.
