Why does sin equal opposite over hypotenuse?

The sine is always the measure of the opposite side divided by the measure of the hypotenuse. Because the hypotenuse is always the longest side, the number on the bottom of the ratio will always be larger than that on the top. So, the opposite side is 6 inches long. Use the ratio for sine, opposite over hypotenuse.

What sine means?

The sine function is defined as the ratio of the side of the triangle opposite the angle divided by the hypotenuse. We know the angle the cable makes with the ocean floor and the length of the cable (hypotenuse). To find the length of the side opposite the angle, d, we use the sine function.
