Answer:
Step-by-step explanation:
Given: 39 = 0.01n
Move the decimal point on each side two places to the right: 3900 = n
4 (of whatever your mathematical unit is)

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
