If you draw a line in the center of triangle ABC then, both sides form right-angled triangles. Therefore, you can use the sine rule to get the length of half of BC and then multiply by 2 to get the length BC. Then, get the height of the line in the center and then use the Pythagoras theorem to get the length of the hypotenuse. The lengths are 7.42units and 10.5units.
