the sum of the interior angles of a heptagon is
180(7-2) = 900°
One angle is missing
x + 120+ 150+ 135 +170 +90 +125 = 900
x = 110
The smallest interior angle will cause the largest exterior angle
so largest exterior is 180 - 90 = 90°
The measures of 6 of the interior angles of a heptagon are: 120°, 150°, 135°, 170°, 90°, and 125°. What is the measure of the largest exterior angle?
90°
80°
75°
85°
