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

Option C is correct.

Step-by-step explanation:

We need to find reference angle and signs of sinФ, cosФ and tanФ

We know that is equal to 150°

and 150° is in 2nd quadrant.

So, Ф is in 2nd quadrant.

And In 2nd quadrant sine is positive, while cos and tan are negative

The reference angle Ф' is found by: π - Ф

=> Ф = 5π/6

so, Reference angle Ф' = π - 5π/6

Ф' = 6π - 5π/6

Ф' = π/6

So, Option C Θ' = pi over 6; sine is positive, cosine and tangent are negative is correct.
