The smaller triangle was dilated to form the larger triangle. What is the value of x? A smaller triangle has side lengths of 5,
riadik2000 [5.3K]

Answer:

x = 7.5

Step-by-step explanation:

Dilation is a transformation in which the size of a given figure is either increased or decreased by a scale factor.

Given that the length of sides of the smaller triangle are; 5, 13, 12.

Given also that the length of the dilated triangle are; x, blank, 18.

Comparing the length of the last sides of the two triangles, we have;

(scale factor x 12) + 12

                        = (\frac{1}{2} x 12) + 12

                        = 6 + 12

                        = 18

Thus the scale factor for the dilation is \frac{1}{2}. So that:

x = (\frac{1}{2} x 5) + 5

   = 2.5 + 5

   = 7.5

x = 7.5

And also,

blank = (\frac{1}{2} x 13) + 13

          = 6.5 + 13

blank  = 19.5

Therefore, the length of the sides of dilated triangle are: 7.5, 19.5, 18
