As we know that the sum of all angles of triangle is 180.
therefore
(x-9)+x+(2x-5)=180
x+x+2x+(-9-5)=180
4x + (-14)=180
4x - 14=180
4x=180+14
4x=194
x=194/4
x=48.5
x-9=39.5
2x-5=92.0

This is a great break down! I learned it in class and just forgot how exactly to solve x. I feel stupid now, especially since algebra is my fave. THANK YOU! <3
