Answer:
Step-by-step explanation:
If arccos (√3 / 2) = β, then cos β = adjacent side / hypotenuse = √3 / 2. This tells us immediately that the adjacent side length is √3 and the hypotenuse is 2. Via the Pythagorean Theorem, we know that the third side is 1.
This information rules out the 1st and 3rd answer choices.
Because cos 30° = adj / hyp = √3 / 2, we can conclude that the correct answer is the 4th one: 30°, 60°, 90°

Answer:
We have been given that Charles has six times as many action figures as Ben
Let Ben has x action figures
So according to question Charles will have 6x.
together the action figures total more than 75



So Ben will have more than
action pictures.
And 

Charles will have more than
.
A) I believe but you might not want to go with it cause I'm not good at math AT ALL:)
26 would 130% of 26%.
20 would be 100% of itself leading us to X being 130%.
That brings us to two equations of 20=100% and x=130%
20/x=100%/130%
20/x=100/130
(20/x)*x=(100/130)*x
20=0.769230769231*x
26/0.769230769231=x
26=x therefor x=26
