Answer:
[tex]100\sqrt{3}[/tex]
Step-by-step explanation:
Remeber that a right triangle with a 30 degree leg is a 30-60-90 traingle, and a 30-60-90 triangle has the following properties.(Check Picture Below)
So since the other leg will be [tex]\sqrt{3}[/tex] times more than the other leg, the exact length of the other leg in the triangle will [tex]100\sqrt{3}[/tex]
The picture is from Study.com, you can check there for more info on special triangles.
Hope this helped.
