Choose 3 different random digits from 0 to 9, @, , . (For example, (59 = 4, = 5, = 3) = ____, (C) = ____, (E = ____ OABCD is a rectangle-based pyramid. The picture on the right is the bird's-eye View from above. Point A is on the xaxis (red), and is (49 meters east of 0. Point C is on the y-axis (green), and is meters north of 0. Each unit i51 meter. The pyramid is (I?) meters tall. (a) At} is projected onto A?!) to become A}. First, sketch this projection and paste it on this answer document). (b) To 3 decimal places, calculate the magnitude of this projected vector. Finally, calculate A}
