Given the triangle below, find sec X, tan X, and cos X in fraction form.

*right triangle, hypotenuse goes from top right to bottom left, bottom side is longer than top side. Top right point is z, left point is X, bottom right angle (the right angle) is Y. The short side, ZY=15, and the hypotenuse, XZ=25*

A. sec X= 5/3, tanX= 3/4, CosZ= 4/3
B. sec X= 5/4, tanX=3/4, cosZ= 3/5
C. sec X=4/3, tanX=3/4, cosZ= 5/3
D. sec X=5/4, tanX= 5/3, cosZ=4/5

So, with the triangle drawn as you have said, with the right angle on the x-axis, you just have a scaled up 3-4-5 triangle, with sides 15,20,25.

sinX = 15/25 = 3/5
cosX = 20/25 = 4/5
tanX = 15/20 = 3/4

Looks like time to review your basic trig functions and the Pythagorean Theorem.
Ok I'm thankful for the help but jeez you don't have to be like that. This is the second time you've done this. Maybe don't be a jerk about it?
Plus you didn't even answer it soooooo...
No, I didn't answer the question, but I gave you enough information so you could complete the solution.

Sorry to be jerk-ish.
