I think the answer would be 2.05 because 6.15/3 is 2.05
All four angles are exterior angles of the quadrilateral.
We know that the sum of exterior angles of any polygon is 360 ° .
So we can add together the four angles and solve for x:
(x+16)+(3x-1)+6x+5x = 360
15x+15=360
15x=345
x=345/15=23 °
Given :
Mr. Turner employer pays 100% of his medical insurance. He has rent of $800 and $600 for car payment, $100 light bill, and $300 car insurance. His payroll and income taxes are estimated to be $287.
To Find :
What is his necessary monthly salary to have a gross income to meet his total expenses including the payroll and income taxes.
Solution :
Minimum salary to bear all expenses is :
S = Basic expenses + Payroll and taxes
S = $( 800 + 600 + 100 + 300 + 287)
S = $2087.00
Therefore, monthly salary is $2087.00 .
Hence, this is the required solution.
