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

0 x 8

x 10

Ох 13

Answer:10

Step-by-step explanation:

Each exterior angle is (3x + 6) °

A decagon has 10 sides

Each exterior angle=360/n

n=number of sides

3x+6=360/10

Cross multiply

10 (3x + 6) = 360

30x+60=360

Collect like terms

30x=360-60

30x=300

Divide both sides by 30

30x/30=300/30

x=10
