Answer:
$5.20
Step-by-step explanation:
Talked on the phone for 14 minutes .
14 - 3 = 11
11 x .35 = 3.85
3.85 + 1.35 = 5.2
Angle 1 would 107° since a and b are parallel. Angle 2 would be 180° - 107° = 73°.
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.
7x2+x-6 is the correct answer
