The sum of the measures of the interior angles is 1.440 degrees. how many sides does the polygon have?

Number of sides of polygon = N =10

Step-by-step explanation:

Given as , the sum of measures of the interior angles = 144 degree

Let the number of sides = N

Now, External angle =

And Interior angle = 180° - Exterior angles

Or, Interior angle = 180° -  

Or , 144° = 180° -  

Or,   = 180° - 144°

Or ,   = 36°

∴ N =

Hence, Number of sides of the polygon = 10   Answer

168

step-by-step explanation:

i am pretty sure that the answer is 168
