Divide the length of the hypotenuse by the opposing side.

If you know the lengths of the three sides of the triangle, the sine of angle X is the ratio of the length of the triangle leg opposite angle X to the length of the hypotenuse. http://en.wikipedia.org/wiki/Sine#Right_triangle_definitions

if i remember it correctly, right angle has a 90 degree angle and that is a constant with sin 0. hehehe...

The sine is the side opposite the angle divided by the hypotenuse of the triangle.

Opposite side divided by hypotenuse.

6172017 Trigonometry is based on a picture of a circle with the radius making an angle with the x axis. You carry this picture in your head, not your calculator. Trig is mostly imagination and the rest memorization. Remember Chief SohCahToa  Sin = Opposite/Hypotenuse  Cosine = adjacent/Hypotenuse  Tangent = Opposite/Adjacent  Also memorize  Sec = 1/Cos  Csc = 1/Sin  Cot = 1/Tan
