If a 225 pound box is resting on a sloping ramp, two forces are "at work" on the box as a result of its weight.
One is the force f2 perpendicular to the ramp and the other, a friction force f1, is parallel to the ramp.
Find the sizes of these two forces if the ramp slopes at an angle of 15 degrees.

See the lesson Using vectors to solve problems in Mechanics: Force in this site.
F1 = 225*sin(15°) pounds.
F2 = 225*cos(15°) pounds.
