**JJ**, Wednesday, February 20, 2013 at 5:44pmIt is always good to draw a picture. You have a right triangle with hypotenuse of 16. The side opposite the angle that you are looking for is 5.

If you take the opp/hypotenuse = sine of the angle

5/16 = sin of angle.

You can use your calculator to find the value of the angle. This is the angle whose sine is 5/16 or .3125.

If you have trouble figuring that out. you can take the sin of each of the angles given and see if that value equals .3125 which is 5/16.
