Problem number 10, Luz looks at the pyramid from above. What does Luz see? Notice that the two gray edges are next to each other in the picture. So they also need to be shown next to each other in the answers. This means that A, B, and E cannot be the right answer. Now let's just figure out how the other two sides appear in relation to the two gray sides. We can think of this edge as the bottom front of the pyramid. That means that the black side is on the left, there's the center, and the white side shown in outline is on the right. We can draw in the two gray sides. And we see that the black side is counterclockwise relative to the gray sides. This is the case in answer C, going from the gray sides to the black sides, we're going counterclockwise. Whereas in D, we would have to go clockwise. So D is not the right answer. The correct answer is C. Luz sees the figure shown in C.
Video Summary
Luz observes the pyramid from above and identifies which view reflects what she sees. The gray edges must be next to each other, eliminating options A, B, and E. Evaluating the positioning of the black and white sides relative to the gray sides, the black is on the left, and the white is on the right from the bottom front perspective. The black side is counterclockwise to the gray sides, matching option C. Therefore, the correct view Luz sees is represented by answer C.
