Answer 1

Answer: All expect cos of theta=17/8

Step-by-step explanation: Fist, let find a equal cos equation. let use the idenitiy($cos^{2}$Ф+$sin^{2}$Ф=1.  $cos^{2}$+15/17^2=1, $cos^{2}$=1-225/289. $cos^{2}$=289/289-225/289.  $cos^{2}$=64/289. sqr root of $cos^{2}$= 8/17.  

Using Other Formulas, Since secant is the reciprocal of cosine. sec(theta)=17/8.   since cosecant is the inverse of sin.  csc(theta)=17/15.

Using the formula sin x/cos x= tan x , $\frac{15}{17}$=$\frac{8}{17}$ =15/8.
