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