tan = opposite/adjacent =3/4
using the pythagorean theorem you get
3^2 + 4^2 = r^2
25= r^2
5 = r (Hypotenuse)
sec = hypotenuse/ adjacent
sec s = 5/4

If the angle is in quadrant I and tan s = ¾, or opposite/adjecent, then Hypotenuse is â(3² +4²) = 5.
With all 3 sides of the right angles known, you can figure out the rest.

sec(s)=1/cos(s) and tan(s) = sin(s)/cos(s) => 3/4
Solve for cos(s) and you get the answer
