You can just guess numbers that could be x, I tried 80 and it got me 32 so I tried 60 and it got me 28 I tried 70 and it got me 30=16+1/5(70)
Answer:
Find the area of table top( circle)
A=πd²/4
A = 3.1415× (90cm)²/4
A= 3.1415× 8100cm²/4
A= 3.1415×2025
A=6361.5375cm²
The area of the table top is 6361.5375cm².
One angle = 360 / n
Let x be the angle and n be the number of sides.
x = 360 / n
nx = 360
now, let's use this:
(2n - 4 )*90 = 1260
2n - 4 = 1260 / 90
2n - 4 = 42 / 3
2n - 4 = 14
2n = 18
n = 9
x = 360 / 9
x = 40 degrees for each exterior angle
so the interior angle's measurement is 140 degrees
So 9 would be the answer
