What is the measure of each angle?

I had a hard time reading the + & - signs in the equations. Look at my notes.

5x - 4 = 95.44°       (Note: Is the - sign correct?)

x - 2 = 17.89°           (Note: Is the - sign correct?)

3x + 7 = 66.67°       (Note: Is the + sign correct?)

Step-by-step explanation:

180 = 5x - 4 + x - 2 + 3x + 7

combine like terms:

180 = 9x + 1

9x = 179

x = 19.89

5x - 4 = 5(19.89) - 4 = 95.44°

x - 2 = 19.89 - 2 = 17.89°

3x + 7 = 3(19.89) + 7 = 66.67°
