A soccer ball is kicked with an initial horizontal velocity of 14 m/s and an initial vertical velocity of 15 m/s.

I have found the initial speed of the ball to be 20.51. That was the easy part. However, the next part is not working out for me. "What is the initial angle θ of the ball with respect to the ground?".

So I tried working backwords to find out what that angle is to the left of the right triangle. I used tanx=15/14. Why does this not work? I get 3.96 which I convert to degrees, to get 227degrees, but thats obviously wrong. Any idea as to where I can begin to solve this question?
