Have figured out that 36 degrees is the minimal angle that the ship can fire to make it over the hill and 76 degrees is the maximum. The ship is safe if it is; closer than 194 meters to the western side and further than 3577 meters. However, the answer in the back of book is; less than 265 and greater than 3280 meters. What am I doing wrong?

An enemy ship is on the east side of a mountainous island. The enemy ship can maneuver to within 2500 meters of the 1800 meter high mountain peak and can shoot projectiles with an initial speed of 250m/sec. If western shoreline is horizontally 300 meters from the peak, what are the distances from the western shore at which a ship can be safe from the bombardment of the enemy ship?

you have to be farther than 2500 meters from the shoreline because of the enemies trajectory. your angle of fire should then be higher than at least 60

Use 45 degrees for the max range of the ships shooting.
