Find cos(C) in the given right triangle.

Understand the Problem

The question is asking to find cos(C) in a right triangle where the side adjacent to angle C (BC) needs to be calculated, and the hypotenuse is given. First, we ned to find side BC using the Pythagorean theorem, then calculate cos(C) using the ratio of adjacent side to the hypotenuse, where cos(C) = Adjacent/Hypotenuse.
