Question

What is the scale factor of Figure B to Figure A?48.6B2510A1021.5A. O 6.25B.O 2.5C.0.16D. 0.4

Answer 1

As per given by the question,

There are given that two traingle, figure A and figure B.

Now,

The ratio of a dimension on figure B to the corresponding dimension on figure A is,

`4\colon10=8.6\colon21.5=10\colon25`

So,

The scale factor is,

`\begin{gathered} k=(10)/(4)=(25)/(10)=(21.5)/(8.6)=2.5 \\ \end{gathered}`

The scale factor of figure B on the figure A is 2.5.

Hence, the option B is correct.
