Finding the value of cosine of my given right triangle

The video tutorial explains how to find the cosine of angle C in a right triangle. It begins by defining cosine as the ratio of the adjacent side to the hypotenuse. The tutorial then identifies the hypotenuse as the longest side opposite the right angle and the adjacent side as the one connecting angle C and the right angle. The cosine of C is calculated using the ratio of the adjacent side (6) to the hypotenuse (10), which is then reduced to 0.6 and further to the nearest thousandth.
