The triangles are similar. <br> What is the value of x?<br><br> x =
saveliy_v [14]

Answer:

x = 23

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

\frac{39}{x-10} = \frac{36}{12} = \frac{15}{5} = 3

multiply both sides by (x - 10)

3(x - 10) = 39 ( divide both sides by 3 )

x - 10 = 13 ( add 10 to both sides )

x = 23
