You would have to find the adjacent and the hypotenuse. For example, if the adjacent was 80 degrees and the hypotenuse 29 you would do this: cos(29)/29 which wiuld give you 0.03. When finding the cosine its adjacent over hypotenuse. For sin its opposite over hhypotenuse and for tan its opposite over adjacent.

How do you find the hypotenuse with a cosine and or sine?
For a right angle triangle:- hypotenuse = adjacent/cosine or hypotenuse = opposite/sine
How do you find the cosin of a right triangle?
put in cosine in your calculator and then take the cosine of the length of the adjacent length over the length of the hypotenuses length
How is cosine defined?
In a right triangle, the cosine of an angle is defined as the ratio of the adjacent side of that angle to the hypotenuse.
How do you find the angles of a triangle that is not a right triangle if you only have the side measurements?
If it's not a right angled triangle and you don't have any of the angles but have the values of all three sides, then you need to use something called the Cosine Rule.
What equation describes the cosine function for a right triangle?
