Respuesta :
Sum of Interior Angles = (Number of Sides -2) • 180 degrees
Sum of Interior Angles = (8 -2) * 180 = 1,080
EACH interior angle = 180 - (360 / 8)
EACH interior angle = 180 - 45 = 135
Sum of Interior Angles = (8 -2) * 180 = 1,080
EACH interior angle = 180 - (360 / 8)
EACH interior angle = 180 - 45 = 135
The sum of the interior angles is 1080 degree and measure of interior angle is 135 degree.
As we know that
Sum of Interior Angles = (Number of Sides -2) • 180 degrees
Since octagon has eight sides. That is n = 8
Now, sum of Interior Angles
[tex]= (8 -2) \times180 \\=6\times180 \\= 1,080[/tex]
And the measure of interior angle
[tex]= 180 - (\frac{360}{n} )\\n=8\\= 180 - (\frac{360}{8} )\\=135[/tex]
Therefore, the sum of the interior angles is 1080 degree and measure of interior angle is 135 degree.
