Determine the value<br> of x in this polygon. (PLATO)
tresset_1 [31]

Answer:

136

Step-by-step explanation:

No matter what the distribution, all of the interior angles of a convex hexagon will add up to 720 degrees. Therefore, if you subtract all of the known angles in this hexagon from 720, you will find x.

720-134-106-117-119-108=136 degrees. Hope this helps!

8c=5c+21 What would that be
NemiM [27]
To solve for C, you have to get both of the numbers with a C on the same side.  So, subtract the 5c from the right side onto the left side.

8c = 5c + 21\\8c - 5c = 5c - 5c + 21\\3c = 21

Then, divide by 3 on each side.

3c = 21\\3c /3 = 21/3\\c = 7

So, c = 7.
