How? you ask…. Well, take a right triangle, whose reference angle is 30 degrees. That means the third angle in the triangle must be 60 degrees. Remember it’s a right triangle so one of the angles is 90 degrees already. Well, by the power of SOH-CAH-TOA, we discover that the sin (30) = ½, and cos (60) = ½. And, 30 + 60 = 90 !Algebra.
