Question

Triangle HIJ is dilated by a scale factor of 3/4 to form triangle H'I'J'. What is the measure of side IJ?

J'I' - 18
J'H' - 20.1
I'H' - 20.1

First, we know that the scale factor for the dilation is 3/4. This means that the ratio of the corresponding sides of the two triangles should be 3/4.

Given:
J'I' = 18
J'H' = 20.1
I'H' = 20.1

Since J'I' corresponds to IJ, we can set up the following equation:

IJ / 18 = 3/4

Cross multiplying, we get:

4IJ = 18 * 3
4IJ = 54
IJ = 54 / 4
IJ = 13.5

Therefore, the measure of side IJ is 13.5 units.
