Figure B is a scaled copy of Figure A. What is the scale factor from Figure A to Figure B?
Please answer fast

4

Step-by-step explanation:

We are told that figure B is a scaled copy of B, which means figure A was enlarged by a certain scale factor to get a similar figure as A, now referred to as figure B.

The scale factor = ratio of any two corresponding sides of both similar figures.

Thus,

Scale factor of the similar figures given = 40/10 = 4.

This means that, figure A was scaled up by 4 times its original size to get figure B. Each side of figure B is 4 × the corresponding side in figure A.

Scale factor = 4

First, let's find the scale of the smaller to the bigger triangle:

6:6+4 = 6:10 = 3:5

3/5 = x/2

6 = 5x

x = 6/5
