Answer:
8
Step-by-step explanation:
The formula for the number of degrees in the sum of the interior angles of an n-sided polygon is ...
sum of angles = 180°(n -2)
Filling in the given value and solving for n, we get ...
1080 = 180(n -2)
6 = n -2 . . . . . . divide by 180
8 = n . . . . . . . . add 2
The polygon has 8 sides.
Tyler finished more of the art project.
Carlos finished 1/3
In terms of percentage 1/3 *100% = 33.3%
Tyler finished 1/2
In terms of percentage 1/2 *100% = 50%
50% > 33.3%
50% is greater than 33.3%
