The scale factor of the similar triangles is: 1/2. The value of x is: 4.5 cm.
<h3>Scale Factor of Similar Triangles</h3>
Scale factor of similar triangles is the ratio of their corresponding sides.
Given the two similar triangles in the diagram attached below, we have the following scale factor as:
Scale factor = 2/4 = 1/2
Therefore:
x = 1/2 × 9
x = 4.5 cm.
Therefore, the scale factor of the similar triangles is: 1/2. The value of x is: 4.5 cm.

2.549 = 2.549
3.207 > 3.027 because 2(in the tenths place) is greater than 0
8.25 = 8.250 because adding a zero at the end of a decimal doesn't make a difference
5.871 > 5.781 because 8(in the tenths place) is greater than 7
9.36 > 9.356 because 6(in the hundredths place) is greater than 5
1.538 < 1.54 because 3(in the hundredths place) is less than 4
7.036 > 7.035 because 6(in the thousandths place) is greater than 5
6.700 = 6.7 because adding a zero at the end of a decimal doesn't make a difference
