Question 630560: You have a heptagon with the following measurements of 6 interior angles: 125º, 130º, 175º, 105º, 165º, 25º. What is the measure of the 7th angle? If it is not possible, write not possible and explain why it is not possible.

You can put this solution on YOUR website! You have a heptagon with the following measurements of 6 interior angles: 125º, 130º, 175º, 105º, 165º, 25º. What is the measure of the 7th angle? If it is not possible, write not possible and explain why it is not possible.
---
sum of the interior angles of a heptagon = (7-2)*180 = 900 degrees
----
Sum of the six given angles: 725
-----
Measure of the 7th angle 900-725 = 175 degrees
