This image of a physics problem shows a block resting on a ramp, pq. ∠p is the angle between the ramp and the horizontal, and bw−→− is oriented vertically. which quantity is equal to cos w? a. sin p b. cos p c. 1 − sin p d. 1 − cos p

From the image given depicting an object on a ramp, we assume angle a to the complementary angle of angle w. another complementary angle of a is let's say b. In this case, we can say that angle w and angle b are the same via alternate interior angles. hence cos W is equal to the sine of its complementary. The answer is A. sin P.
