Circumference = pi * diameter, in this case you have:
c=8p in
If you look at the figure, you will see that there is an angle opposite each angle whose value we have. Therefore, just do (3x+2x+x)·2= 6x·2=12x
Now, 360/12=30°
x=30°

Answer:
<h3 /><h3>The number is 162</h3>
Step-by-step explanation:

5/9 × x = 90
5/9x = 90
Multiply through by 9
That's
5x = 810
Divide both sides by 5
5x/5 = 810/5
x = 162
Therefore the number is 162
