Ф =5π/6
The reference angle is the smallest angle that the terminal side of the angle makes with the x-axis.
Given that here π/2 < Ф < π, the angle is in the second quadrant.
In the second quadrant the signs are:
sine positive
cosine negative
tangent negative.
Furthermore, the reference angle is π - Ф = π - 5π/6 = π/6.
Then,
sin Ф = sin π/6 = 1/2
cos Ф = - cos π/6 = -√(3) / 2
tan Ф = - tan π/6 = -√(3) /3
Answer:
solve for x and that should help match the equation to the correct grapgh, hope this help!
Step-by-step explanation:
Answer:
17 Units
Step-by-step explanation:
Since the y coordinate is the same for both points we only need to know the change in the x coordinates to find the distance between these two points.
5+12=17
So these two points are 17 units apart.
