Answer 1

Answer:

The answer is 115.70

Explanation:

Answer 2

Answer:$\theta =64.29^{\circ}$

Explanation:

Given

Vector Points -1.55 units along x-axis

i.e. 1.55 units along negative x-axis

and 3.22 units along Y-axis

Direction of vector

$\tan \theta =\frac{3.22}{1.55}$

$\theta =tan ^{-1}(2.077)$

$\theta =64.29^{\circ}$

Where $\theta$ is the angle made by vector with x-axis as shown in the diagram
