There are three sides, hypotenuse, opposite and adjacent. But the adjacent and opposite are not fixed sides: it depends on which of the two acute angles you are examining.
For either of the non-right angles, the adjacent side is the one which forms the angle, along with the hypotenuse. For the given angle θ, the length of the adjacent side compared to the hypotenuse (adjacent/hypotenuse) is the cosine (cos θ).

What is the adjacent and opposite sides of a right triangle?
For any angle in the triangle that is not a right angle, the opposite side is the side does not touch the angle and the adjacent side touches it and is perpendicular to the opposite side. The third side is the longest side and is the hypotenuse
If you divide length of the opposite side of an angle in a right triangle by the length of the adjacent side what value do you get?
It is a tangent.
How do you determine what side of the triangle is the hypotenuse?
Given a right triangle, the hypotenuse is the longest side or simply the side opposite the 90o angle.
A triangle has an angle of 15 degrees. The side opposite the angle is 1.2m in length. How would you find the base of the triangle Not the hypotenuse?
Assuming this is a right triangle. the tan of an angle is the side opposite over the side adjacent. We know the side opposite, we need to find the side adjacent, we will assign this unknown side temporarily as x. tan(15) = 1.2 / x x = 1.2 / tan(15) x (the side adjacent) is approx. 4.49 m
How do you find the cos of a triangle?
Adjacent side / Hypotenuse
