in maths we can measure angles using bearings. the angle is always measured from north to the given line so you have to start by drawing a vertical line up from the point you're asked to do the calculation on. then you measure the angle from the north line you've drawn to the line you have. you should give your answer as 3 numbers, followed by the degrees sign so you might need a 0 at the front e.g. if it's only 45 degrees it will be 045 *degrees sign.
