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.

- Exterior angle what am I doing wrong? -

Where are your angles being measured? Why should the sum of two interior angles equal an exterior angle?
