Which equation is considered simpler to start with when solving for time?

• The quadratic equation

• The y equation

• The identity equation

• The x equation

What trigonometric identity is used to simplify the y equation?

• 1 + cot^2 = csc^2

• sin = cos * tan

• sin^2 + cos^2 = 1

How many solutions are found for the angle, and why?

• No solutions, as the equation is unsolvable.

• Three solutions, due to the cubic nature of the equation.

• Two solutions, because the equation is quadratic.

• One solution, because the equation is linear.

What is the relationship between the two angle solutions found?

• They are equal.

• They are complementary.

• They are supplementary.
