Find the interior angle on a regular polygon with 45 sides...

Mathematics
1 answer:
PolarNik [594]3 years ago
3 0

The exterior angles sum to 360º. Let x be the measure of each exterior angle. Then

45x = 360º  ==>  x = 8º

Then each interior angle (which is supplementary to an exterior angle) has measure (180 - x)º, so they have measure 172º.

If the side length is increased by a factor of 3, how much larger is the perimeter of a face of the new cube?
Luden [163]
The <span>perimeter of a face of the new cube is 8 times larger than the previous cube.
</span>Let us say, the side of cube before increase is "a"
Then perimeter of the cube = 12a ,

because the cube has 12 sides.
And perimeter of a face of cube = 4a
Now, the side length is increased by factor of 3 i.e. new side is 3a
Thus, perimeter of new face of the cube = 4*3a = 12a

Therefore, the new perimeter is larger by = 12a - 4a = 8a
