The hypotenuse is labeled 65, the opposite side is labeled 33, and the adjacent side is labeled 56. The angle where the adjacent side and the hypotenuse meet is labeled with the theta symbol. The right angle is marked with a small box.

Use the inverse of cosine to find the approximate measure of the missing angle θ
