HYP = 3.9
ADJ =3.6
OPP = 1.5
My choices are
1. 12/13
2. 5/13
3. 13/12
4. 12/5

Best ResponseYou've already chosen the best response.0Well 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

Best ResponseYou've already chosen the best response.0Secant is the reciprocal of cosine so whatever cosine would be, say 3/4, secant would just be the reciprocal so 4/3

Best ResponseYou've already chosen the best response.2yes not cosine if sin = 1/csc then csc =1/sin

Best ResponseYou've already chosen the best response.2first of all you need to know \[\rm sin \rm \theta = \frac{ opposite }{ hypotenuse }~~~~ \cos \theta = \frac{ adjacent }{ hypotenuse } ~~\tan \theta = \frac{ opposite }{ adjacent }\]

Best ResponseYou've already chosen the best response.2sec is reciprocal of 1/cos now look at the diagram cos theta =?

Best ResponseYou've already chosen the best response.0The secant would be the Hypotenuse/Adjacent So you would divide 3.9/3.6 which equals about 1.083 Then divide out the other answers to see which combination matches 1.083

Best ResponseYou've already chosen the best response.0@hiltbrandj09 Okay I get it. So it would be 13/12 right?
