Answer:
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.

First, you would need to determine how many questions he got correct.
30 - 12 = 18
Next, you would need to create an equation for this problem. Let x represent the unknown percentage.
=
Now, you would cross multiply.
30x = 1,800
The last step would be to isolate the x. To do this, you would divide both sides of the equal sign by 30.
x =
60Ahmad got 60% of the questions correct. I hope this helps!
$1.00 because the first ounce is 0.40 then you have to times the other 3 ounce by 0.20 then u would have $1.00
