Answer:
A choice
Step-by-step explanation:
sec is defined as 1/cos.
cos is again defined as adjacent to hypotenuse.
We know that adjacent is x and hypotenuse is r.
Therefore:- cos is x/r
Now sec is 1/cos = 1/(x/r)
1 ÷ x/r is 1•r/x
Thus:-
sec is r/x
A ray in mathematics starts at a point and extends infinitely in one direction away from that point
it differes from a line because a line extend indefinitely in both directions
the sun ray starts from the sun and does not pass through the sun so it starts from a point (the sun's surface) and extends indefinitely into space unless it hits something (planets, black holes, endpoint)
The solution to what you put down is 1,3
