What's the fastest way to do this problem? I know only the long way. What is the perimeter of right triangle ABC?

    it's a 30-60-90 triangle so you should be able to list the 3 sides

    yes, unless you "memorize" 1/sqr(3) = sqr(3)/3

    but it does not take too long 6 + 6/sqr(3) + 12/sqr(3) 6+ 6 sqr(3)/3 + 12 sqr(3)/3 6+ 2 sqr(3) + 4 sqr(3) 6+ 6 sqr(3)

    the way you waste time is not noticing it's 30-60-90 and not being able to do the problem at all

    There isn't any faster way. You just have to do the math to find the length of the missing sides and add them all up.
