Which figure accurately represents the two components of Vector A?

Vectors are measures which have both a magnitude and a direction. An example of a vector in aviation is the wind velocity with its direction.

The practical use for vectors is that two (or more) vectors (components) acting on a body can be added (or subtracted) to calculate the total effect of the vectors. When two vectors (components) are added, then their combined effect produces another vector, called "the resultant".

The vectors (components) must be added (combined) in a correct sense:

  • The head of one vector (component) must lie off the tail of another vector (component) (head - to - tail).
  • The resulting vector (resultant) is a line from the tail of the first vector to the head of the last one (first tail - last head).
For this question, the vector A is a resultant represented in Figure 1, which consists of two components meeting the requirements described above.
