Example 1

For a fixed angle measure such as `50°`, what is the ratio of the opposite side divided by by the hypotenuse? Solution: You can answer this question by entering `sin50°` into your scientific calculator.
`sin50°=0.766`
This also means if you draw a `50°` angle with the length of the hypotenuse equals `1` unit and you measure the opposite side, the length will be 0.766 unit.
