One interior angle of a polygon is equal to 800 and each of the other interior angles are 128 degrees. find the number of sides of the polygon.

6

Step-by-step explanation:

Given information:

Interior angle of a polygon cannot be more that 180°.

One interior angle =

Other interior angles are  =

Let n be the number of sides of the polygon.

Sum of interior angles is

Combine like terms.

          .... (1)

If a polygon have n sides then the sum of interior angles is

          .... (2)

Equating (1) and (2) we get

Isolate variable terms.

Divide both sides by 52.

Therefore the number of sides of the polygon is 6.

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
