Each exterior angle of a regular decagon has a measure of (3x + 6) °. What is the value of x? open study

The sum of exterior angles for a polygon is 360°. This is a decagon, having ten sides, so each exterior angle will be 360/10=36°, so we can say:

3x+6=36 subtract 6 from both sides

3x=30 divide both sides by 3

x=10°
