How do you find the hypotenuse using trigonometry?
The cosine ratio can be used to calculate the length of one of the shorter sides (legs) of a right triangle, or to find the length of the hypotenuse. In both cases you need to know the cosine ratio for one of the smaller angles. If you are finding an unknown leg length, then the hypotenuse must be known.

How do you find the hypotenuse of a right triangle?
The hypotenuse is always opposite the right angle and it is always the longest side of the triangle. To find the length of leg a, substitute the known values into the Pythagorean Theorem. Solve for a^2.

How do you find the hypotenuse of a triangle using angles?
To find the length of the adjacent side when the length of the hypotenuse and an angle are known, use the cosine of the angle. The length of the adjacent side is 3.277’, or 3’ 3 5/16”. Find the lengths of the two unknown sides (the angle given is the reference angle for the side).
