    Law of sines

    A plane is headed due east with an airspeed of 340 miles per hour. Its true course, however is at 98 degrees from due north. If the wind currents area consults 55 miles per hour, what are the possibilities for the ground speed of the plane?

    I do not know hoe to draw the triangle to start this problem. I also do not understand what it means what are possibilities for ground speed.

    Thank you
