90degrees, and 1 side length? sorry were doing review stuff in math
180 - 90 = 90
that would be a angle, not side length, also there are 3 angles in a triangle

if you ment 180-90-other agngle=angle you dont know then thanx but not exactly what i was asking 4
but which do i use, sin, tan or cos?
also how do i set it up, like is it something like
Con 90 degrees = con 45 degrees = con 45 degrees
