Adjacent angles are angles that are side by side (right next to each other). They share a side. #7 and 11 are pairs of adjacent angles.
Vertical angles are angles that are directly across from each other. They are the same angle. #8 and 9 are vertical angles.
#10 and 12 do not fit either of these descriptions so they are neither.
The slope is equal to 5/2.
0.7859
First: We would need to figure out which number is in the thousandths place.
Number in the thousandths place: 5
Next: You would look at the number directly behind your 5, which would be your 9.
Rule: 4 and below leave it alone, 5 and up move it up.
Since the number is 9 you would bump the number in front of it up.
You would get: 6
Your answer would be: 0.786
HOPE THIS HELPS! ^_^
