Question

Find the direction angle of -12i - 35j

Answer 1

`\theta=71.07^(\circ)`

Explanation:

The given vector is :

v = -12i - 35j

We need to find the angle direction of v.

The general vector is given by :

v = xi+yj

The direction angle is :

`\theta=\tan^(-1)((y)/(x))`

We have, x = -12 and y = -35

So,

`\theta=\tan^(-1)((-35)/(-12))\\\\\theta=71.07^(\circ)`

So, the required direction angle is
`71.07^(\circ)`.
