So you know all angles in a triangle add to 180 degrees and you have x + 3x + 2x which adds to 6x so you do 180/6 to get x = 30 and c = 2x so you do 30 x 2 which is 60 degrees. Hope this helps :)
All you do is add a zero on the end of this to make it to the nearest hundreth: 34.8(0) That means that this is the correct order: 34.8, 36.43, 36.29 or Option B
