A scale factor of 1/3 is used to make a reduction of the original triangle
1 answer:
Answer:
<h2>8 units.</h2>Step-by-step explanation:
The complete question is
<em>A scale factor of 1/3 is used to make a reduction, as shown in table below.</em>
<em>What is the base of the reduced triangle?</em>
- <em>4</em>
- <em>8</em>
- <em>9</em>
- <em>21</em>
According to the given table, the original base is 24. If the given scale factor is applied, the reduced base would be
Remember that a scale factor is a number that multiples the figure, a scale factor can reduced or amplify a figure.
Therefore, the reduced base is 8 units.
