The sum of the angle measures in a dodecagon is 1,800 degrees
i hope i helped
Well first we should simplify:
![\sqrt[5]{3}](https://tex.z-dn.net/?f=%20%5Csqrt%5B5%5D%7B3%7D%20)
+
![\sqrt[2]{3}](https://tex.z-dn.net/?f=%20%5Csqrt%5B2%5D%7B3%7D%20)
This turns into:
so for this equation, I would do 7/8 = 72/x
1 72
- = -
8 x
Cross multiply to get 72 * 8 = 1x
solve for X 576 = x
(2j+7)(2j−7)
=(2j+7)(2j+−7)
=(2j)(2j)+(2j)(−7)+(7)(2j)+(7)(−7)
=4j2−14j+14j−49
=4j2−49
