If sin (theta) = sqrt5 / 3 and cos (theta) = 2 / 3 which of the following is tan (theta)?

sqrt(5) / 2
Thank you! But Can you please explain to me how you got it or show ur work?
for this kind of problem, draw the right triangle.
cosθ = 2/3
means that the adjacent side is 2 and the hypotenuse is 3.
sinθ = √5/3
means that the opposite side is √5 and the hypotenuse is 3.
But, then you knew that already, since the opposite side would be
√(3^2-2^2) = √5
Si, since tanθ = opposite/adjacent, you have Damon's result.
Now it's time to review the basic trig functions, and then this kind of problem will be easy from now on!

Thank u so much!!
Actually I just used the trig identity tan = sin/cos
same difference :)
same difference :)

Yep, honors student is right.
Thank you honors student!!
Thank you honors student! Haven't been here in a long while. Man I missed this.
