Answer:
Option B
Step-by-step explanation:
A unit circle means radius of the circle = 1 unit
Let a terminal point on the circle is (x, y) and angle between the point P and x-axis is θ.
Center of the circle is origin (0, 0).
Therefore, ordered pair representing the terminal point will be (OP×Cosθ, OP×Sinθ) = 
OP.Cosθ = 1×Cosθ = 
Cosθ =
θ = 
, 
where n = integers
Similarly, OP×Sinθ = 1×Sinθ = -
Sinθ = -
θ = 
, where n = integer
Common value of θ will be, θ = 
Option B will be the answer.

Answer:
trisect the median. The centroid is 1/3 its length from the side.
Step-by-step explanation:
The centroid divides each median into parts with a ratio of 2:1. If you trisect the median, the centroid will be 1 unit from the side and 2 units from the vertex.
Answer: 42
Step-by-step explanation:
The ratio scoops of detergent to scoops of fabric softener is 2:3.
If there are 28 scoops of detergent remaining, the number of scoops of fabric softener will be needed will be:
= (28/2) × 3
= 14 × 3
= 42 scoops of fabric softener
Use the Pythagorean theorem:
Answer:
x = 5
Step-by-step explanation:
It can help a lot to draw a diagram, if one is not provided. There is no requirement that it be drawn to scale. It just needs to be able to show the given information.
Given angle QRS is exterior to the triangle. Its measure is the sum of the two given remote interior angles:
8x -9 = (3x -11) +(3x +12)
2x = 10 . . . . . . . add 9-6x and simplify
x = 5 . . . . . . divide by 2
