Calculate Toolbar positioning next to a rotated element

Question

I’m kind of bad at math, but I imagine this is something based on cosine and tangent based on the hypotenuse radius. It should be considered that when the angle is 0 or 90 degrees, Toolbar should be next to the selected element, such as a small distance, that is, a distance less than if it was at 45º.

How could you make a calculation to position Toolbar always on the right side, when changing the angle of an element?

Based on element angle:

function position(current, x, y, area_x, area_y, scale) { 

     //não sei se retornar sempre positivo seria o ideal
     var angleElement = Math.ceil(current.get('angle'));

     if (scale != null && x && y) {

        //mostrando ângulo: 341
        console.log(angleElement);

        if(angleElement > 30 && angleElement < 50) {
           x += 20;
        }
        if(angleElement > 280 && angleElement < 340) {
           x += 20;
        }

        //posicionamento X e Y do toolbar em relação ao objeto rotacionado
        btnLeft = area_x + ((x + 10) *  scale);
        btnTop = area_y + ((y - 20) * scale);


     }
    return {
       left:btnLeft,
       top:btnTop
    }

}

Element of fabricjs

//tamanho da área da div onde está o canvas:

var area_x = $('.paper-area').offset().left;
var area_y = $('.paper-area').offset().top;
//o elemento selecionado...
var current = canvas.getActiveObject();
var x = current.oCoords.tr.x;
var y = current.oCoords.tr.y;
var scale = 1;
var objPos = position(current, x, y, area_x, area_y, scale);

//resultado...
console.log(objPos.left, objPos.top);

Here is a video how it’s working today.

Managed to do, thanks @Augustovasques, I ended up finding the way from what you said:

var bound = current.getBoundingRect(),
    ang = Math.round(current.get('angle')),
    distance = (ang > 72 && ang < 102) ? 50 : 24;
btnLeft = area_x + ((bound.left + bound.width + distance) * $scope.zoomParams.scale);
btnTop = area_y + ((bound.top) * $scope.zoomParams.scale);

The video of the final result.
