I try to solve it but I don't know where to start. Please explain to find the area of the triangle.
I can only find this part and don't know how to find other sides to find the require areaIf you've tried anything at all, please show it to us, because we may be able to show how to use it. There isn't just one way, and the best way for you to use is the one you see for yourself.
Also, please ask any specific questions you have about the problem -- for instance, did you wonder why we aren't told anything about the vertical positioning of the rightmost point of the shaded triangle? Wondering that can help you get a clue to the problem!
But I started by finding the legs of the right triangle at the lower left. Let us know if you see any way to approach that, so we can help you do so.
Thanks. That's a good diagram, which is the start of any solution.I can only find this part and don't know how to find other sides to find the require area
You know that the area of a triangle is 1/2 bh, right?I'm sorry but I don't get it. Would you mind pointing out that on diagram. And I think I can't use the normal way of finding the area of triangle since there's no proof that the required triangle is a right triangle. so I think I need to use the 1/2× a×b× sinQ. But I can't find the proper way to find the necessary sides and angle.
Oh I finally got the point what I've been missing. I didn't realise the way to find the actual height of the triangle and now I just remember it. Thank you sir. This means a lot to meYou know that the area of a triangle is 1/2 bh, right?
If you turn your picture on its side so that FE is the base, what is h?
