Answer:
1) The angle would be 150 degrees
a) coordinates would be ( 
, 
)
b) Trigonometric ratios:
sin:
cos:
tan: 
csc: 2,
sec: 
cot: 
Explanation:
simplifys to 
which has a reference angle of 
. We can take the coordinates of and make the x value negative to find the correct coordiantes. Then, using those coordinates, plug the into the trigonomic equations.
For example, sin in opposite/hypotenuse. So sin = 1/2 divided by 1. Then you can find the rest of the equations that way.
cos= adjacent/hypotenuse
tan= sin/cos
csc= hypotenuse/opposite
sec= hypotenuse/adjacent
cot= cos/sin

Answer:
C. Method of loci
Explanation:
The method of loci is a method of memorizing information by placing each item to be remembered at a point along an imaginary journey. The information can then be recalled in a specific order by retracing the same route through the imaginary journey.
