Michael was using the triangle below to prove the law of cosines. His first step was to draw a line from ∠C perpendicular to side c. When he does this what should he label the 2 parts of the line that used to be just c?

Question
Michael was using the triangle below to prove the law of cosines. His first step was to draw a line from ∠C perpendicular to side c. When he does this what should he label the 2 parts of the line that used to be just c?
(a)The distance from ∠B to the perpendicular line could be represented by x, and the distance from ∠A to the perpendicular line could be represented by c-x.
(b)The distance from ∠B to the perpendicular line could be represented by c, and the distance from ∠A to the perpendicular line could be represented by c-x.
(c)The distance from ∠B to the perpendicular line could be represented by x, and the distance from ∠A to the perpendicular line could be represented by c-h.
(d)The distance from ∠B to the perpendicular line could be represented by x, and the distance from ∠A to the perpendicular line could be c+x.
