1)

A 30-60-90 triangle has a specific ratio in which its side lengths are defined. It is a \(1:\sqrt{3}:2\) ratio. Knowing this set ratio, it is easy to determine that the hypotenuse is double the length of the shorter leg. Therefore, the hypotenuse length is 16 meters long!

 

2) 

This question is very similar to the previous triangle, except that we are dealing with a different special right triangle. A 45-45-90 triangle's ratio of the side lengths is \(1:1:\sqrt{2}\). If one of the lengths of the legs is 8 inches, then the hypotenuse has length \(8\sqrt{2}\text{ inches}\).

 

3) 

It appears as if this question has a formatting issue.
