I need help with this math problem - angles

I have a flu and I cant think, i cant find info on how to do this so i need help with this: http:// tinypic com/r/50ffrb/7 get rid of the spaces, yahoo wont let me post a link

Set it up like this:
14x+(8x+4)=180
22x+4=180
-4 -4
22x+0=176
22x=176
/22 /22
x=8

So your answer is x=8.

Supplementary= <180

14x+8x+4=180
x=176/22
x=8 degrees(symbol)

14x + 8x + 4 = 180 degrees
22x + 4 = 180
22x = 176
x = 176/22
x = 8

14x+(8x+4)=180
22x=176
x=8 degree
