An early warning radar station expects an enemy attack over a mountain range. The mountain range is 30 miles from the radar station. The attack is expected to fly right over the top of the mountain, which would put the jet at an altitude of 12,000 feet. For the best chance of success, the radar should be pointed directly at the incoming jet. At what angle of elevation should the radar be aligned? Round to one decimal.
