Making a logical answer from this. If one of the angles are already 40 degrees, that means the same angle on the other side is 40 too. 40 plus 40 is 80. A straight angle I believe measures to 180 degrees, so, you're still missing the other 100 degrees..which means the different two other angles are each 50 degrees(?)

585 = 45x
585/45 = 45x/45
x = 13
