The two equal angles would be represented by x each and then the 3rd angle would be 2x + 16 to represent the 16 more than twice. The sum of the three angles is 180 degrees, so 1x + 1x + 2x + 16 = 180. combine like terms (x's). Now you should have a two-step equation of ...

Math
Since the angles are all compared to the second angle, let x (also known as 1x)= 2nd angle; therefore first angle which is twice the second = 2x and the third angle which is three times the second = 3x. All angles of a triangle have a sum of 180 degrees. 1x + 2x + 3x = 180 now...
