Question

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

Answer 1

do you know where 5pi/6 is on the unit circle. and what a reference angle is?

Answer 2

2nd quadrant and the angle is 150

Answer 3

alright. so your reference angle would be the distance from the x axis(if you want to call it that) in radians. so do you know what that would be from 180?

Answer 4

30 degrees

Answer 5

so what is 30 degrees in radians. and what would your signs be on sin cos and tan in Q2?
