Best ResponseYou've already chosen the best response.0you can use the rule a squared + b squared = c squared. where a and b are the shorter lengths of the rightangled triangle and c is the length of the hypotenuse. because you already have the lengths of AC and BC, you can easily find AB. then using AB, you can do the next step. make sense?

Best ResponseYou've already chosen the best response.0AC/AB = AB/AD then plug in the info we know 36/(18*sqrt(3)) = (18*sqrt(3))/AD and then solve for AD

Best ResponseYou've already chosen the best response.036*AD = (18*sqrt(3))(18*sqrt(3)) 36*AD = 18*18*sqrt(3)*sqrt(3) 36*AD = 18^2*(sqrt(3))^2 36*AD = 324*3 36*AD = 972 I'll let you finish
