use graph paper chose a suitable scale to draw the lines that represent the magnitude of forces (example: 1cm:10N), using ruler, draw the line B and put arrow to show the direction of the force, using protractor, measure the angle between line B and A then draw the second line and arrow to show direction, draw the new dotted line with arrow of B with the same scale , draw the new dotted line with arrow of A with the same scale and connect it with line B, Finally draw the magnitude of resultant force with correct scale and calculate its value.
