The sum of the measures of the interior angles of a polygon of n sides is
180(n - 2)
If the polygon is regular, all angles are congruent, and each angle measures
[180(n - 2)]/n
Set the measure of one angle equal to 140, and solve for n, the number of sides.
[180(n - 2)]/n = 140
180(n - 2) = 140n
180n - 360 = 140n
40n = 360
n = 9
The number of sides is 9.
First, Multiply
2 hours x 4 days = 8 hours
Subtract,
28 hours - 8 hours = 20 hours
Divide
20 hours ÷ 4 days = 5 hours each day.
Check you work by Multiplying and adding
5 hours x 4 days = 20
20 hours + 8 hours = 28 hours
Heather worked 5 hours each dinner shift
so the best equation to set up here would be 4560x12=N. (N can be the variable for your yearly salary) and all thats left is to solve so 4560x12=54,720 so you make about $54,720 per year
hope this helps
