Homework Help: Exterior angle what am I doing wrong?

Posted by bart on Sunday, May 16, 2010 at 1:30am.

Find the measure of the indicated exterior angle.

Exterior angle is: 197-5n
Two interior angles are: 5n+21 and n+11

I set it up as:
197-5n=5n+21+n+11
197-5n=6n+32
165=11n

but this does not make sense.
