Best ResponseYou've already chosen the best response.1Well, if given the perimeter of an equilateral triangle, you can find the lengths of the sides by using the formula \[S_{\text{Triangle}} = \frac{P}{3}\] dw:1357829776184:dw Afterwards, you'll have to draw the altitude which divides the base of the triangle in half. dw:1357829954412:dw Furthermore, you'd have to use Pythagorean Theorem to find the the length of the altitude

Best ResponseYou've already chosen the best response.1dw:1357830348662:dw so, how would i make this into a pythagoream theorom?

Best ResponseYou've already chosen the best response.1Split the bigger triangle into two smaller ones. Then just solve for one of the missing sides. The missing side is the altitude of course.

Best ResponseYou've already chosen the best response.1i got a=24.6 .. is that right?

Best ResponseYou've already chosen the best response.1c = 22 is the hypotenuse, right? So either leg has to be less than that. In other words a < c

Best ResponseYou've already chosen the best response.1So there's no way that a = 24. 6

Best ResponseYou've already chosen the best response.111x11=121 and 22x22=484, then i added them together and 605 and the squareroot of 605 was 24.6 :c

Best ResponseYou've already chosen the best response.1a^2 + 11^2 = 22^2 a^2 = 22^2  11^2 a^2 = 484  121

Best ResponseYou've already chosen the best response.1a^2 + 11^2 = 22^2 a^2 = 22^2  11^2 a^2 = 484  121 a^2 =121(4  1) a^2 = 121(3) a = sqrt(121*3) a = sqrt(11^2)sqrt(3) a = 11sqrt(3)
