Question

The length of the hypotenuse of a 30-60-90 triangle is 18. What is the perimeter?

I have no idea how to start this or how to do this.

Answer 1

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

Answer 2

Would all the sides equal 180?

Answer 3

The options.

Answer 4

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.

Answer 5

Thank you!

Answer 6

oops for the answer i meant to put 27 9 square root 3 (i forgot to add the 9 to 18) sorry
