One way to do this is use the fact that the exterior angles of all polygons add up to 360 degrees
So an exterior angle of a regular octagon  = 360 / 8 = 45 degrees.
So each interior angle = 180 - 45 = 135 degrees

so total measure of all angles in octagon = 8 * 135 =  1080 degrees

−3 2/3=x−1 1/4 pls help
slega [8]

Answer:

  • - 2 5/12

Step-by-step explanation:

  • −3 2/3 = x − 1 1/4
  • x = - 3 2/3 + 1 1/4
  • x = - 2 - 2/3 + 1/4
  • x = - 2 - 8/12 + 3/12
  • x = - 2 - 5/12
  • x = - 2 5/12

Simplify the equation 32^3/5
scoundrel [369]
Ok so to simplify 32^3/5, you will need to know the steps, so I'll tell u the step by step solution. ;D

So Step 1: You have to <span>Raise 32 to the 3rd power:

</span><span><span>1.1 </span>    32 = 2</span>⁵
(32)³ = (2⁵)³ = 2¹⁵

<span>the equation has ended on step 1, so now is:

</span><span>  2</span>¹⁵
<span>------
  5
</span>
Now step 2:
Simplify it 

(you can't simplify this equation but these is the steps you gotta do on other equations so I'm just giving an example.)

  2¹⁵
------
  5

So basically your final result is:

  2¹⁵
------
  5

=====End=====

Hope you understand it :D
