Assume this example of a 30-60-90 Triangle, we have a triangle with the known short side of 5 m, and a hypotenuse of 10 m. In this example, it is easy to find the missing side’s length. By taking the length of the short side and multiplying it by the square root of 3.
a = 5 m
2a = 10 m
a√3 = ?
(5) √3 = 8.66 m
The answer to this problem is that the missing side equals 8.66 m.
