In the triangle ABC, the angle at B measures 110°, the angle at C is 40° and the side BC = a is 6.8 units in length. (i) Draw the triangle. (Your drawing does not need to be to scale.) (ii) Use the Law of Sines to find the lengths of all sides and the sizes of all angles. Specify values to one decimal place. (iii) Check your answers in part (ii) using the Law of cosines.
