You would flip the triangle along one side to form an equilateral triangle

Would all the sides equal 180?

The options.

anonymous · Answer

the ratio of a 30-60-90 triangle is 1-square root 3 - 2 so if the hypotenuse is 18 (ratio equivalent 2) the other sides are 9 and 9 square root 3. add them up to get the perimeter which would be 18 9 square root 3.
