Question

When Θ = 5 pi over 6, what are the reference angle and the sign values for sine, cosine, and tangent?

Answer 1

Θ' = negative pi over 6; sine and cosine are positive, tangent is negative.
Θ' = 5 pi over 6; sine and tangent are positive, cosine is negative
Θ' = pi over 6; sine is positive, cosine and tangent are negative
Θ' = negative 5 pi over 6; sine is positive, cosine and tangent are negative

Answer 2

@mathmale can you help me?

Answer 3

\(\Huge\color{green}{ \rm \frac{ 5π }{ 6}=\frac{ 5(180) }{ 6}=150 }\)

more help needed ?

Answer 4

that isn't one of the answer choices though and i really don't get how to do this
