Question

The components of vectors B and C are given as follows:
Bx = -6.3 Cx = -3.6 By = -8 Cy = +7.4
The angle (less than 180 degrees) between vectors B and C, in degrees, is closest to: The components of vectors B and C are given as follows:
Bx = -6.3 Cx = -3.6 By = -8 Cy = +7.4
The angle (less than 180 degrees) between vectors B and C, in degrees, is closest to: The components of vectors B and C are given as follows:
Bx = -6.3 Cx = -3.6 By = -8 Cy = +7.4
The angle (less than 180 degrees) between vectors B and C, in degrees, is closest to:

Explanation / Answer

Vector B lies in the third quadrant and vector C lies in the second quadrant. The angle between B and the negative x axis is arctan (8/6.3) 51.770. The angle between C and the negative x axis is arctan (7.4/3.6) 64.050. The angle (less than 180 degrees) between vectors B and C, is closest to (51.770 + 64.050) = 115.820
