the x - vector or y - vector that can be broken down into an overall vector is called the resultant vector.
true
false

Explanation:

Question 1

When facing [N 60° E], turning 90° counter - clockwise (left) means we are now facing a direction. The original direction [N 60° E] has an angle of 60° from the north towards the east. A 90° left - turn changes the reference. The new direction is [N 60° E] rotated 90° counter - clockwise. The angle from the west towards the north is 30°, so the new direction is [W 30° N].

If we are pointing south and then turn 20° west, the direction is described as starting from the south and then moving 20° towards the west. In the format [S x° W], where x is the angle from the south towards the west. Here, x = 20°, so the direction is [S 20° W].

The x - vector and y - vector are called the components of the vector. The overall vector (the vector that is made up of the x and y - vectors) is called the resultant vector. The statement has it backwards.

Answer:

True
