Answer:
Step-by-step explanation:
Hello. Would love to try and help, your screenshot is not showing up when I click on it though.
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.

Mary drove 6 hours
Step-by-step explanation:
The magnitude and the direction angle for the resultant vector are 10N and 120degrees respectively
The formula for calculating the resultant vector is expressed as:

Given the following distances:
u = -5√3 feet (west direction)
v = 5 feet
Substitute the given values into the formula above;

The magnitude of the resultant vector is 10feet
Get the direction:

Since tan is negative in the second quadrant, hence;

Hence the magnitude and the direction angle for the resultant vector are 10N and 120degrees respectively.
