In the figure, a person standing at point A notices that the angle of elevation to the top of the antenna is 45(degrees) 30'. A second person standing 31.0 feet farther from the antenna than the person at A finds the angle of elevation to the top of the antenna to be 43(degrees) 10'. How far is the person at A from the base of the antenna? Round to the nearest whole number.
