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 which you would subtract 16 from both sides first and then divide both sides of your equation by the coefficient of x (number of x's).
