Question

Need help finding answer

Answer 1

cscθ=
`(√(145) )/(9)`

Explanation:

If the terminal side's point is defined as P = (x, y), in this case P = (8, 9)... then the trigonometric function of cscθ = r/y.

r =
`\sqrt{x^(2) +y^(2) }`

So for the given point:

r =
`\sqrt{8^(2) +9^(2) }`

r =
`√(64 + 81) =√(145)`

cscθ=
`(√(145) )/(9)`

Rate me and tell me if it's correct!! :)
