      A right triangle is drawn with angle α opposite a side with length 33, angleβ opposite a side with length 56, and hypotenuse 65. Find the sine and cosine of α andβ. You may have noticed that in the above example that . cos(α) =sin(β) and cos(β) =sin(α). This makes sense since the side opposite α is also adjacent to β.
