Let the  measure  of  the  smallest  angle  =  A

 

Let the measure  of the largest  angle  be =  A  + 4D     

 

Where D  is the  common difference in the arithmetic sequence

 

And  we  know  that

 

(A + 4D)  - A   = 44     simplify

 

4D =  44   divide  both sides  by 

 

D  = 11

 

And the sum of the interior angles =  540°.....so we have that

 

A  + (A + 11)  + (A + 22)  + (A + 33)  + (A + 44)   = 540

 

5A  + 110  =  540       subtract 110 from both sides

 

5A  = 430     divide  both sides  by  5

 

A =  86°

 

cool cool cool
