Use the given point on the terminal side of angle Θ to find the value of the trigonometric function indicated.

Question

Here is all that is given: csc Θ ; (2√5,4)

Answer 1

csc(theta) = 1/sin(theta) = hypotenuse over opposite side = sqr(x^2+y^2)/y = 6/4 =3/2= 1.5

sqr((2sqr5)^2+4^2) =sqr(20+16) = 6 = hypotenuse
