1)The x and ycomponents of a velocity vector of 100 N at 240 degrees would be?
2) A man pushes a lawn mower across the lawn exerting 5 N of force along the handle at an angle of 25 degrees with the ground. What is the xcomponent of the force he exerts?

1) The answer depends upon what reference direction the 240 degrees is measured from, and whether + means couterclockwise or counterclowise. In mathematics and physics, polar direction angles are measured counterclockwise from +x. I assume you are dealing with a Force (F) vector and that is how the angle is measured.
Then the vector is in the third quadrant and
Fx = 100N cos 240 = 100N cos 60 = 50N
Fy = 100N sin 240 = 100N sin 60 = ?
2) 5N cos 25
