Question

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?

Answer 1

sum of interior angle of heptagon=(7-2)×180°
=900°
the remain interior angle=900-120-150-135-170-90-125
=110°
the smallest interior angle is 90°
so the largest exterior angle=360-90
=270°

Answer 2
