Question

Figure A is a scale image of Figure B. What is the value of x?​

Answer 1

x = 5.4

Explanation:

since the figures are scaled factors of each other then they are similar.

the ratios of corresponding sides are therefore in proportion, that is

`(x)/(7.2)` =
`(3)/(4)` ( cross- multiply )

4x = 21.6 ( divide both sides by 4 )

x = 5.4
