Answer:

The value of x is 10/7
Step-by-step explanation:
Given:
4) Triangle ABC is similar to triangle DEF
side AB = 5, side BC = x
side EF = x + 2. side DE = 12
To find:
to draw the triangles, write the proportion and solve for x
First, we need to draw the triangles using the given information:
In similar triangles, the ratios of the corresponding sides are equal
For Triangle ABC similar to triangle DEF
AB corresponds to DE
BC corresponds to EF
AC corresponds to DF
The ratio of the corresponding sides will give the proportion:


Finally, we will solve for x:
