Answer:
2x-6+2=14
Step-by-step explanation:
2x-6+2=14
2x-4=14
2x=14-4
2x=10
x=5
Both angles 2x+6 and 96 shown are vertically opposite angles and vertically opposite angles are always equal
so 2x+6 should be equal to 96
so 2x + 6 = 96
Now we have to solve for x here and have to get x by itself on left hand side
So first get rid of +6 by doing its opposite -6 on both sides
2x + 6 -6 = 96 -6
2x = 90
Now to get x by itself we have to get rid of 2, for that divide both sides by 2

x = 45
Hence proved that x = 45
The exact name of the postulate isn't coming to mind, but it's the postulate that any three points that are not on the same line will form a unique plane. A plane in mathematics is a flat surface that extends in all directions.
A little tip is this
if its like 1.4 inches it goes to 1 inch but if it goes to 1.5 inches it goes to two
