cosine = adjacent side divided by hypotenuse
sine = opposite side divided by hypotenuse
tangent = opposite side divided by adjacent side
you are dealing with a right triangle.
the side opposite the 90 degree angle is the hypotenuse.
for example:
iif your triangle is ABC and angle C is the 90 degree angle, then cosine (A) is equal to the length of the side opposite angle A divided by the length of the hypotenuse which is the side opposite angle C.
cosine = adjacent side divided by hypotenuse
sine = opposite side divided by hypotenuse
