Question 1103460
<br>
Note that this problem is about a right triangle; so all the angles are acute, and the values of all the trig functions are positive.<br>
You can solve this quickly if you recognize 5 and 13 as two numbers in a Pythagorean Triple.<br>
If not, then...
use sin^2x+cos^2x=1 to find sinx; then
tanx = sinx/cosx
secx = 1/cosx
cscx = 1/sinx
cotx = 1/tanx
