Answer:

x = 23

Step-by-step explanation:

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

[tex]\frac{39}{x-10}[/tex] = [tex]\frac{36}{12}[/tex] = [tex]\frac{15}{5}[/tex] = 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

5 x 3 = 15 12 x 3 = 36 your answer would be 13 because 13 because 13 x 3 would be 39
