Best ResponseYou've already chosen the best response.1the height is 6 so....... 6b/2 = 30 3b = 30 b = 10 more than the other one

Best ResponseYou've already chosen the best response.0But 10 is the leg not a base. So it would make triangle not a square right?

Best ResponseYou've already chosen the best response.16*16  = 48 for the 'area' of the triangle 2 90  48 = 42 6(7) = 42...... small side = 7 large side = 23 then right?
