What are your "doubts"? What have you tried? What did you obtain? On what basis have you decided that you were "unsuccessful"?Hi, i have some doubts to find the perimeter of this triangle. a tried a lot of things, but without successful.
Mario's diagram shows AB = tg (alpha)
Anybody know what d'heck that means?
