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.

Step-by-step explanation:
Answer:a²=b²+c² in a right angle triangle so answer is root 136
Step-by-step explanation:
First figure out what 851 minutes 473 equals to, which is 378
So both sides of the equation should equal to 378
Plus 470 and 378 together
Which equals to 848
So the answer is eight hundred and forty eight
