Answer 4

Well secant is 1/cosine. And I don't know if you ever learned this but my teachers always referred me back to SOHCAHTOA,
Sine= opposite/hypotenuse
Cosine = adjacent/hypotenuse
Tangent = opposite/adjacent

So from that you see that cosine is A/H and so secant would be H/A because it's the reciprocal

So you have to see which answer is the same ratio as 3.9/3.6
