Dmitrij [34]

The correct option is B which is the value of PG is 3 units.

Given

The scale factor of the dilation of segment HG is 1/6.

If PG' equals 0.5 units,

<h3>What is the scale factor?</h3>

The scale factor is a measure for the identical shapes, which look identical but have various scales or measures.

The scale factor of the dilation of segment HG is 1/6.

By the rule of scale factor;

\rm \dfrac{PG'}{PG}= SF = \dfrac{1}{6}

Where SF represents the scale factor.

Solving for PG, we get:

\rm \dfrac{PG'}{PG}=\dfrac{1}{6}   \\\\ \dfrac{0.5}{PG} = \dfrac{1}{6}\\\\ 0.5 \times 6= 1\times PG\\\\ PG = 3

Hence, the value of PG is 3 units.
