The vector has components (-25, 45). The angle θ with the positive x-axis is given by θ = arctan(45/-25). This angle is in the second quadrant, so θ = 180° + arctan(45/-25) = 119°.

The Angle Between = −(25 M)+ (45 M)and the Positive °\degree°

The Angle Between = −(25 M)+ (45 M)and the Positive $\degree$
