Answer:
x = 25
Step-by-step explanation:
Sun of the exterior angles of a quadrilateral = 360°
Therefore:
x + 40 + 6x + 2x + 20 + 3x = 360
Add like terms
x + 6x + 2x + 3x + 40 + 20 = 360
12x + 60 = 360
12x = 360 - 60
12x = 300
x = 300/12
x = 25
This is actually a very simple problem when you understand how to do it.
First, I would add the 12 to both sides.
Equation would now look like this x/6=24
Then I would do the inverse (opposite) of division which is multiplication.
So multiply 6 to both sides so we can get the x alone. 6*12=144
Now x is alone, and X = 144.

Answer:
Step-by-step explanation:
The description is too ambiguous to reconstruct the diagram. You need to post the actual diagram.
That diagram is just one way to view division by a fraction. An easier way: DIVIDING by a fraction is the same as MULTIPLYING by the upside-down fraction. For example,
(1/2) ÷ (1/4) = (1/2) × (4/1) = 2
That doesn’t help you answer this particular question, though.
