Question

Does anyone know what’s the answer? lost my revision guide‍♀️

Answer 1

see the explanation

Explanation:

we have that

The scale factor is

`1(1)/(2)=1.5`

we know that

To find the length of the segment CZ, multiply the segment CR by the scale factor

so

`CZ=CR(1.5)`

substitute

`CZ=4(1.5)=6\ units`

therefore

Roy's diagram is not correct, because on the graph, Roy draws the length of the CZ segment equal to 10 units instead of 6 units.

Roy is using a scale factor equal to 2.5 instead of 1.5.
