Divide 3 on both sides
x=3.33
Answer:2
Step-by-step explanation:
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

Answer:
4 + (2 x 3)^2
Step-by-step explanation:
4 + 6^2
4 + 36
40
Its a because it is less than 30 but the others are more than 30, that was easy.
