Question

What is the scale factor from triangle ABC to triangle DEF? (Hint: new/original) B 6 fi E 3 ft А F 10 ft 5 ft 2 = 2009 1/2 = 5096 3/2 = 150% d 2/3 = 66 2/396

Answer 1

Given data:

The given triangles.

The expression for the ratio of the triangle.

`(DE)/(AB)=(DF)/(AC)=`

Substitute the given values in the above expression.

`\begin{gathered} \frac{3\text{ ft}}{6\text{ ft}}=\frac{5\text{ ft}}{10\text{ ft}} \\ (1)/(2)=(1)/(2) \end{gathered}`

Thus, the scalle factor is 1/2 which is 50%, so correct option is (b).
