The first angle is 27, the second is 135 degrees and the third is 18 degrees. This is because the first angle is x, the second is 5x and the third is 2/3x. In a triangle all the angles add up to 180 degrees. So you add x + 5x + 2/3x and that is equal to 180. Then once you solve for x (you get the first angle) and can find out the rest.
