$(10x + 9) \degree + (3x + 13) \degree + (x + 4) \degree = 180 \degree \\ 10x + 3x + x + 9 + 13 + 4 = 180 \degree \\ 14x + 26 = 180 \\ 14x = 180 -26 \\ 14x = 154 \\ x = \frac{154}{14} \\ \boxed{x = 11}$

To test subtitle 11 in x, your angles should add up to 180 degrees

Because when the denominator is bigger in a fraction it actually makes it smaller
