A dart is thrown at a dartboard 2.37 m away. When the dart is released at the same height as the center of the dartboard, it hits the center 0.447 sec. At what angel relative to the floor was the dart thrown.

t = sqrt(2h/9.8)
0.447s = 0.452 H
H = 0.988

now find the angle,
use your calculator and plug in
arctan (0.988 / 2.37 )
should be 22.6 degrees.
Thanks :)
