If ABC is ~ to DEF then
AB is ~ to DE
35~x and
BC is ~ to EF
30~15
30/2= 15 So 35/2= 17.5
AB is ~ to DE

30/2= 15 So 35/2= 17.5
Both triangles are similar because of angle angle similarity.
So you can just make a proportion.
[tex] \frac{CB}{BA} = \frac{FE}{x} [/tex]
Insert the numbers:
[tex] \frac{30}{35} = \frac{15}{x} [/tex]
Cross multiply: 30x = 520
x = 17.5
