Question

Need help finding answer

Answer 1

Answer:

cscθ= $\frac{\sqrt{145} }{9}$

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 = $\sqrt{x^{2} +y^{2} }$

So for the given point:

r = $\sqrt{8^{2} +9^{2} }$

r = $\sqrt{64 + 81} =\sqrt{145}$

cscθ= $\frac{\sqrt{145} }{9}$

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