What is the equation for determine the angle measures?

(7x - 9) degree + 4x = ____ degree

1 answer

To determine the angle measures in this equation, you need to solve for x.

Given: (7x - 9) + 4x = ____
Combine like terms: 7x + 4x - 9 = ____
Combine the x terms: 11x - 9 = ____

Therefore, the equation to determine the angle measures is 11x - 9.
