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 ,
(15)/(17)=
(8)/(17) =15/8.
