an angle of 305 from the east is normally assumed to be counter-clockwise from the east side of the x-axis.

your angle will therefore be in the 4th quadrant because it is greater than 270 and less than 360.

the reference angle would be equal to 360 - 305 = 55 degrees.

the hypotenuse of the triangle formed from that angle would be 14.7 km.

the x component would be equal to 14.7 * cosine(55) = 8.431573614.

the y component would be equal to 14.7 * sine(55) = 12.04153505.

here's a sketch of the angle with the x and y component.

the x component is going towards the east.
the y component is going towards the south.

the coordinates of the terminal point of the line of travel is (8.431573614, -12.04153505)

that point is 14.7 km from the originating point whose coordinates are (0,0).
