Using equivalent angles, we have that the measures are given as follows:
Each angle on the second, third and fourth quadrants will have an equivalent on the first quadrant.
120º is in the second quadrant, hence the equivalent on the first quadrant is:
180º - 120º = 60º.
The sine on the second quadrant is positive, hence:
The cosine on the second quadrant is negative, hence:
The tangent is given by the <u>sine divided by the cosine</u>, hence:

Answer:
15m
Step-by-step explanation:
For every second, the boy walks 1.5 m
So 6 x 1.5 m equals 9 m total
For every second, the girl walks 2m
So 6 x 2 m equals 12 m total
The boy walked North, so it would look like he is walking upward
While the girl walking West looks like she is walking to the left
Finding the distance between them would look like solving a right triangle
We're gonna use the Pythagorean theorem
12² + 9² = distance²
144 + 81 = 225
√225 = 15
