Csc(tan^1 square root 17 divided by 8)
Please help fast!!!

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.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
