Asked by Sasha

Find x and y components of a vector which is 10 units in length and 40 degrees below the +x axis.

I honestly don't even know how to begin this problem .. Please help me !

did you try drawing the figure? You just wind up with a right triangle, where one angle is 40° and the hypotenuse is 10.

x = 10 cos40°
y = -10 sin40°

Looks like time to review your trigonometry.
