The sum of the interior angles of a polygon is 1080 degrees. How many sides does the polygon have?
postnew [5]

9514 1404 393

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.

How to convert 264 yds/1 s to mi/day?
dusya [7]

Answer:

12,960\ \frac{miles}{day}

Step-by-step explanation:

we know that

1\ mile=1,760\ yards

To convert yards to miles multiply by 1/1,760

1\ hour=3,600\ seconds

1\ day=24\ hours

so

(24)3,600=86,400

1\ day=86,400\ seconds

To convert seconds to day multiply by 1/86,400

In this problem we have

264\ \frac{yd}{sec} =264\ \frac{(1/1,760)}{(1/86,400)}=264\ (\frac{86,400}{1,760})=12,960\ \frac{miles}{day}
