Answer:
6
Step-by-step explanation:
Let the missing side be represented as x.
Applying the triangle proportionality theorem, we have:
[tex] \frac{15}{x} = \frac{14 - 4}{4} [/tex]
Solve for x
[tex] \frac{15}{x} = \frac{10}{4} [/tex]
Cross multiply
[tex] x(10) = 4(15) [/tex]
[tex] 10x = 60 [/tex]
Divide both sides by 10
x = 6
