Best ResponseYou've already chosen the best response.1If it's a 306090 triangle, that means that the appropriated ratios of the lengths of triangle sides, opposite from the 30 degree angle, 60 degree angle, and 90 degree angle, are x, x*sqrt(2), and 2x, respectively. You have the value of the hypotenuse, which corresponds to the side opposite of the 90 degree angle, which is 2x. You can quickly solve for x, getting 9. Then, summing all the sides gets you the perimeter formula, which is: \[Perimeter = x + x \sqrt 2+2x\] Knowing that x = 9, simply plug in for X and solve the equation to get the perimeter of the triangle!

Best ResponseYou've already chosen the best response.0\[\large \sf 18 (H)~+~\frac{1}{2}18(SL)~+~\frac{1}{2}18 \sqrt{3}(LL)\]

Best ResponseYou've already chosen the best response.1My apologies, @LegendarySadist had it correct that I had incorrect. The aforementioned side X*sqrt(2) should be X*sqrt(3).

Best ResponseYou've already chosen the best response.0It would be \[\large \sf Perimeter~=~x+x\sqrt{3}+2x\]
