The direction of any vector (force, velocity, acceleration, etc) exists between two components x-component and y-component. Since the acceleration in x-component is equal to zero so the direction of acceleration vector is purely directed towards y-component only which is 90 degree. Actually you don’t need to solve it using the inverse tan because there is no acceleration in x direction, and because of that you can immediately state that the angle is equal 90 degree towards positive y-direction because the acceleration component in y is positive.
How is the acceleration 90deg? 12.8/0 is an undefined value.
U literally need not solve it coz the acceleration has only one component, that is, at the y comp.

Why is it 90°? Its not possible to divide 12.8 by 0.

How to find ay, anyone pls help me
take the second derivative of the x and y components.
