Best ResponseYou've already chosen the best response.0CD = BD  BC so let's first try to find BC

Best ResponseYou've already chosen the best response.0mm that was just to point out that to find CD (the answer) we should try finding BC and BD using what we know about triangles :)

Best ResponseYou've already chosen the best response.0compare the my drawing to the given picture :) the 200 is where the "x" is right? and BD is where the "x sqrt(3)" is

Best ResponseYou've already chosen the best response.0since we are doing proportions, x is 1 so 200 1  =  BD sqrt(3)

Best ResponseYou've already chosen the best response.0good! now CD = BD  BC so subtract the two numbers we got :)
