That is a dodecagon, so x without context is 150.

Answer:

x = 150

Step-by-step explanation:

The regular poligon shown in the image has 12 angles so it's a dodecagon

A dodecagon's interior angles is calculated with the following formula:

(n-2)180 (n is the count of angles)

10*180 = 1800 now this is the sum of all 12 angles' measure to find the value of x we divide this sum by 12

1800/12 = 150 this is the value of x

HELP ASAP! Write an equation where the solution is b= -6. Include like terms and fractions! Thanks in advance

ryzh [129]

First, I'd like to state there are many possibilties to for this solution.

Okay, 9/3 + 3 = -1b

Lets check.
PEMDAS!
9/3 is = 3

So:
3 + 3 = -1b

Then combine like terms:
6 = -1b

Following PEMDAS, divide -1 on both sides so..
-6 = b or b = -6

So, 9/3 + 3 = -1b works!!!
