    Major props to anyone who can solve this

    I know the answer and how to do this, but I am curious to see if anyone else is able to reason out the answer with plain old geometry:

    You have a triangle, UVW. Sides UV and UW are equal in length. Now assume there is a line from W to side UV called WX, and a line from V to side UW called VY. Now suppose there is another line, call it XY. Angle YVW is 60 degrees, angle VWX is 70 degrees, angle UVY is 20 degrees, and angle XWY is 10 degrees. What is the degree of angle YXW?

      I believe I could solve this but I don't think I'm reading the problem correctly to draw the triangle. I'll get back to it.

          Would you be nice and draw it fur us? u_u; ... I can't put the angles on the correct places xD.

              You'll want to draw this out for yourself anyway -- the answer is relatively messier.

                      Re: Major props to anyone who can solve this

                      is this right so far.. i can't figure out whether angle U should be 70 or 20



                      And is that bold green the angle YXW you're referring to..?

                      EDIT **** i ****ed up

                          OMG! ... The answer is...

                          It isn't a triangle! =0

                                  yeah, none of these numbers seem to really work out at all rubix... are lines WX and VY drawn at right angles to their respective sides?

                                      Triangles are 180 degrees, you have 200+ one Luna.

                                              fix'd.. what messed me up was that i assumed the lines were right angles

                                                  ten degrees.

                                                  OR 60 O.O

                                                  That is one screwed up triangle.. o.o

                                                          Nope, everything I said was correctly stated. Please read more carefully.

                                                          The problem would not be solvable btw if the lines were perpendicular to the sides, lol, wouldn't even be a real triangle I think O.o
