Answer:
The surveyor is 36.076 kilometers far from her camp and her bearing is 16.840° (standard form).
Step-by-step explanation:
The final position of the surveyor is represented by the following vectorial sum:
(1)
And this formula is expanded by definition of vectors in rectangular and polar form:
(1b)
Where:
- Resulting coordinates of the final position of the surveyor with respect to origin, in kilometers.
- Length of each vector, in kilometers.
- Bearing of each vector in standard position, in sexagesimal degrees.
If we know that
,
,
and
, then the resulting coordinates of the final position of the surveyor is:

![(x,y) = (35.618, 22.257) + (-25.166, 12.274)\,[km]](https://tex.z-dn.net/?f=%28x%2Cy%29%20%3D%20%2835.618%2C%2022.257%29%20%2B%20%28-25.166%2C%2012.274%29%5C%2C%5Bkm%5D)
![(x,y) = (10.452, 34.531)\,[km]](https://tex.z-dn.net/?f=%28x%2Cy%29%20%3D%20%2810.452%2C%2034.531%29%5C%2C%5Bkm%5D)
According to this, the resulting vector is locating in the first quadrant. The bearing of the vector is determined by the following definition:


And the distance from the camp is calculated by the Pythagorean Theorem:


The surveyor is 36.076 kilometers far from her camp and her bearing is 16.840° (standard form).
