Explanation:

Given:

Magnitude of the vector=10 units

Rectangular components of the vector=8 along x axis and 6 along y axis

To find:

We have to find the angle made by the vector at x and y axis

Solution:

Let Angle made with x-axis = \alpha=α

Therefore

\ {Tan} \alpha= Tanα= =\frac{6}{8}=

8

6

=\frac{3}{4}=

4

\alpha=37^{\circ}α=37

Let Angle made with y-axis =\beta

\tan \beta=tanβ= =\frac{8}{6}=

6

8

=\frac{4}{3}=

3

\beta=53^{\circ}β=53
