Answer:

Step-by-step explanation:
From the given figure it is clear that the stop board is a regular hexagon and ∠I is an exterior angle of the regular hexagon.
Exterior angle of a regular polygon with n sides 
In a regular hexagon number of sides: n =6
Exterior angle of a regular hexagon 
Since ∠I is an exterior angle of the regular hexagon, therefore,
.
We cannot simplify it because the denominator does not have a common factor with the numarator.
The answer to this expression would be 1.2x
Well I can still answer that question without the following and it will be 44,000
