Answer:
A: Three-fifths
Step-by-step explanation:
I have attached an image to depict this question.
We can see that the point at which the radius goes on the unit circle is a coordinate (x, y)
We are told this coordinate is (0.6, 0.8)
Now, in these type of unit circle diagrams;
x = cos θ and y = sin θ.
Thus;
cos θ = 0.6
cos θ = 6/10
Simplifying gives;
cos θ = 3/5
