canvas - Find new point based on relative angle and distance in javascript

Question

Hi how to find the new point based on relative angle and distance in the graph system. My drawing looks like below

Lets say when I change angle between two points (A and c) to 180 the drawing should change to below

I tried to find new point by using below method but its giving wrong values.

let A={x:97,y:445},
    B={"x":99,"y":325},
    C={"x":218,"y":242}; 
function findNewPoint(point, angle, distance) {           
     angle = angle * 0.0174533;
     let x = Math.round((Math.cos(angle) * distance) + point[0]);
     let y = Math.round((Math.sin(angle) * distance) + point[1]);

     return [x, y];
}
let newPoint=findNewPoint([B.x,B.y],180,145);
line(B.x,B.y,newPoint.x,newPoint.y)

When I draw the line by using B and newPoint the drawing looks like below:
