A plane rises from take-off and flies at an angle of 4° with the horizontal runway. When it has gained 450 feet, find the distance, to the nearest foot, the plane has flown. An airplane is at vertex B of a right triangle that has a horizontal side A C, a vertical side B C of length 450 feet, and a dashed hypotenuse A B of unknown length c that rises from left to right. Angle C is the right angle and angle A measures 4°.
