Find the measure of each exterior angle and interior angle of a regular 1.octagon 2. decagon . pls write the formula to find it too

Exterior angle of any polygon = 360 / number of sides

For an Octagon its 360 / 8 = 45 degrees and a decagon its 360/10 = 36 degrees.

The interior angle = 180 - exterior

so for Octagon it = 135 degrees and decagon = 144 degrees
