Math problem

[Stuffz]

easy.

Let's call the cathetus a and the hypotenuse c

a / sin opposite angle = c / sin 90 (I don't know what of those two the opposite angle is because you didn't provide that information)

now just change the equation that c (the hypotenuse we're searching for) is on one side and the all the other stuff on the other.

You should end up with something like this

a / sin opposite angle * sin 90 = c
