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

Answer:B = 10
