A pentagon is a closed 5 sided polygon.

A regular polygon has all sides equal as well as all angles equal.

°The formula to find the sum of all angles of a polygon is = (n-2) ×180

So for a pentagon, n= 5

So the sum of all the angles must be (5-2)× 180= 3 × 180 = 540.

Now as it is a pentagon, it shall have 5 vertices.

So there are 5 angles in a pentagon and all must be equal.

Hence each interior angle must be 540/5 = 108

So for a regular polygon with 5 sides must have each interior angle = 108

Log 54 round to the nearest thousand. <br><br>I got 1.73239
Nonamiya [84]

Type into your calculator (if you haven't already): log 54.


My result: was similar to yours.


Note, however, that we're supposed to round off these results to the nearest thousandths (not thousand).


Your 1.73239 would need to be rounded off to 1.732, with 2 being the nearest thousandths.
