**rbowh**, Saturday, April 6, 2013 at 10:37pmDraw this on a graph. Put point A on the positive y-axis. From A, draw a line that looks to represent 80 degrees, to the x-axis at point B.

The distance from the origin to B is what you want to find.

In that right triangle with right angle at the origin, sin 80 degrees = x/400. Solve for x.
