The scale that maps Figure A onto Figure B is I :6. What is the value of X?

To find the value of X, we need to look at the scale factor given and see how it applies to the dimensions of the figures.

In this case, the scale factor is 1:6. This means that every unit on Figure A corresponds to 6 units on Figure B.

Let's say the length of a side on Figure A is X. According to the scale factor, the corresponding length on Figure B would be 6*X (since 1 unit on Figure A corresponds to 6 units on Figure B).

Therefore, X is the length on Figure A, and 6*X is the length on Figure B.

Since the problem does not provide any specific dimensions for Figure A or Figure B, we cannot determine the exact value of X without more information.
