Hello, iam Mary Kelsey, Have a pleasant day.
What Is The Formula For Cos Θ? [Solved]
It can be abbreviated as Cos(θ) and looks like this: Cos(θ) = adjacent/hypotenuse. In other words, it takes the length of the adjacent side (the side next to the angle) and divides it by the length of the hypotenuse (the longest side of a right triangle).
