Question

If A=2i+3j. The angle between A and y axis is​

Answer 1

60 degree

Explanation:

probably right

Answer 2

We know that

The tangent of the angle is opposite

$A_{x}$ over adjacen $A_{y}$

$tan(/) = \frac{ A_{x}}{ A_{y} }$

$tan (/) = \frac{2}{3}$

Ꮎ$= {tan}^{ - 1} ( \frac{2}{3} )$

Hence, the angle is ${tan}^{ - 1} ( \frac{2}{3} )$
