Figure A's base is 9 and its side is 2.5. Figure B's side is 5 so, what is the value of X?

To determine the value of X, we need to find a similar ratio between the sides of Figures A and B.

The ratio between the sides of Figure A can be calculated by dividing the side length by the base length.

For Figure A: 2.5 / 9 = 0.2778 (rounded to four decimal places)

To find the corresponding value of X for Figure B, we need to multiply the base length of Figure B (since the ratio is based on the base length) by the ratio found above.

For Figure B: X = 0.2778 * 5
X = 1.3889 (rounded to four decimal places)

Therefore, the value of X for Figure B is approximately 1.3889.
