Step 2: now dividend is and divisor is
Hence the result will be .
Answer:
1620 degrees.
Step-by-step explanation:
In a polygon the number of sides = the number of angles.
Each external angle = 360 / 11 = 32 8/11 degrees.
Each internal angle = 180 - 32 8/11 = 147 3/11 degrees
So sum = 147 3/11 * 11
= 1617 + 3
= 1620 degrees.
