What is the least angle measure by which this figure can be rotated so that it maps onto itself? 45° 90° 180° 360°

D. 360°

Step-by-step explanation:

We have been given an image. We are asked to find the least angle measure that will map the given figure onto itself.

We can see that our given polygon is an irregular polygon.

To map the given polygon onto itself, we have to rotate it a full round, that is 360 degrees, therefore, the least angle that maps the given polygon onto itself is 360 degrees and option D is the correct choice.

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
