Answer:
you will draw a number line 0-10 starting on the number 8 you will make a dot and then put the arrow toward the right make sure it is a closed circle not an opened one.
Step-by-step explanation:does that makes sense
I believe it is x=6 because 13-7=6
Answer:
x = 64
Step-by-step explanation:
The sum of the interior angles of a quadrilateral = 360°
Sum the given angles and equate to 360
x + 2x + 114 + x - 10 = 360, that is
4x + 104 = 360 ( subtract 104 from both sides )
4x = 256 ( divide both sides by 4 )
x = 64
Add up all of the sides and you will get the ratio
