Answer:

Option D

Step-by-step explanation:

We have that:

csc(x) = 1/sin(x)

Then:

csc(  tan(√(17)/8)^-1 )

To use the inverse tangent function, you can go to the "inv" button in your calculator, and then use go to the "tan" button.

This is equal to:

= csc( 27.26°)

= csc(27.26°)

= 1/sin(27.26°) = 2.18

And we know that:

(9*√17)/17 = 9/√17 = 2.18

Then the correct option is D.
