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:

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.

7 5/6 - 3 1/12 what does this equal as a fraction in simplest form

KengaRu [80]

For this case we convert the mixed numbers into fractions:

$7 \frac {5} {6} = \frac {6 * 7 + 5} {6} = \frac {42 + 5} {6} = \frac {47} {6}\\3 \frac {1} {12} = \frac {12 * 3 + 1} {12} = \frac {36 + 1} {12} = \frac {37} {12}$

Rewriting the expression:

$\frac {47} {6} - \frac {37} {12} =\\\frac {12 * 47-6 * 37} {6 * 12} =\\\frac {564-222} {72} =\\\frac {342} {72} =$

We simplify:

$\frac {171} {36} =\\\frac {57} {12} =\\\frac {19} {4}$

Thus, the simplified form is: $\frac {19} {4}$

Answer:

$\frac {19} {4}$

About 500,00 people voted what could be the exact number of people

Afina-wow [57]

Your decimal is in the wrong place.
However, assuming the number is 50,000, the answer could be 49987.

Assuming the number is 500,000, the answer could be 499954.
