Answer:

cscθ= [tex]\frac{\sqrt{145} }{9}[/tex]

Step-by-step 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 = [tex]\sqrt{x^{2} +y^{2} }[/tex]

So for the given point:

r = [tex]\sqrt{8^{2} +9^{2} }[/tex]

r = [tex]\sqrt{64 + 81} =\sqrt{145}[/tex]

cscθ= [tex]\frac{\sqrt{145} }{9}[/tex]

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