Answer:
Measure of the side, x = 5.25 units
Step-by-step explanation:
Figure B is a scale image of figure A.
That means figure B is an image and figure A is a pre-image.
Scale factor for the dilation from figure A to figure B = 1.75
Scale factor = [tex]\frac{\text{Side of image B}}{\text{Side of pre-image A}}[/tex]
1.75 = [tex]\frac{x}{3}[/tex]
x = 1.75 × 3
x = 5.25 units
Therefore, measure of the side figure B is 5.25 units.
