Find the measure of the indicated exterior angle.
Exterior angle is: 1975n
Two interior angles are: 5n+21 and n+11
I set it up as:
1975n=5n+21+n+11
1975n=6n+32
165=11n
but this does not make sense.

Exterior angle what am I doing wrong?  drwls, Sunday, May 16, 2010 at 7:28am
165 = 11 n makes sense if n = 15
Where are your angles being measured? Why should the sum of two interior angles equal an exterior angle?
