The west tower and east tower are 15 miles away from each other. A fire is 41 degrees north of east and 56 degrees north of west to form a triangle with the fire. A forest ranger in the west observation tower spots a fire 41° north of east. Fifteen miles directly east, the forest ranger in the east tower spots the same fire at 56° north of west. How far away is the ranger who is closest to the fire? Approximate the distance by rounding to the nearest hundredth of a mile. 9.91 mi 11.87 mi 12.53 mi 18.95 mi
