Choose 3 different random digits from 0 to 9, (8), , (D). (For example, (39 = 4, (CD = 5, (I3) = 3) G) = ____, = ____, (D) = ____ OABCD is a rectangle-based pyramid. The picture on the right is the bird's-eye VlEW from above. Point A is on the x-axis (red), and is (E) meters east of 0. Point C is on the y-axis (green), and is meters north of 0. Each unit isi meter. The pyramid is meters tall. (a) A} is projected onto Ail) 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}. (c) Make up a question, which has |AE'| |AB| as its answer. The unit of work is Joule
