it depends on what you're trying to solve for.

is it the hypotenuse or is it the opposite side?

if you are given a right triangle, then you have a 90 degree angle and two other angles that are acute.

you can find the sine, cosine, or tangent of any of those other two acute angles by using trigonometry.

here's a reference that might help.

if you can be more specific as to what you're trying to solve for, i might be able to help you.

is 50 the length of the adjacent side?
is 86 the angle that has 50 as the adjacent side?
which other side of the triangle are you trying to solve for?
is the triangle a right triangle or some other type of triangle?
