Updated: 10/23/2022

The cosine of an angle is the ratio of the adjacent side to the hypotenuse

only when the angle is in a right triangle. (Otherwise, how would you know

which side is the "hypotenuse" ?)

I have a right angled triangle which i know all the angles of. I have the length of one side which is adjacent to the right angle. How can I work out the length of the hypotenuse and the other side?

Use tangent to find the other leg, and the sine or cosine to find the hypotenuse.
