If the angle of elevation of the sun is 42 degrees , what is the length of the shadow on the level ground of a man who is 6.1 feet tall

Draw it out on a piece of paper to help you see the triangle you are looking at.

From there it is just a matter of figuring out which side of the triangle you want and what trig functions will get you there.

Post back and let us know what you have found once you have drawn it out (we won't do your homework for you, but we will help you with it).
