Question

Let cos Y =.98 what is CSC Y?

Answer 1

to get cscY, you have determine the length of x
then use cscY = 100/x = 100/... = ?

Answer 2

* have to

Answer 3

use the pythagorean theorem :
x^2 = 100^2 - 98^2 = (100+98)(100-98) = 198 * 2 = 396
x = sqrt(396) = sqrt(36 * 11) = sqrt(36) * sqrt(11) = 6sqrt(11)

so, cscY = 100/x = 100/6sqrt(11)

Answer 4

I got 5.05 not sure I m right

Answer 5

if you want rationalize it, just multiply by sqrt(11)/sqrt(11)
cscY = 100/6sqrt(11) * sqrt(11)/sqrt(11) = 100sqrt(11)/(6*11) = 100sqrt(11)/66
