A pilot was flying a small plane towards an oil spill at an altitude of 10,000 ft. He found that the near edge of the spill had an angle of depression on 58 degrees and the far edge of the spill had an angle of depression of 44 degrees. What is the width of the spill? (Find the horizontal distances away from the near edge and from the far edge. Then subtract these two amounts to get the distance across.)
