Answer: It's 18.
Step-by-step explanation: The sides of the smaller triangle are 1/3 as long as the sides of the bigger triangle. So, you just multiply 6 and 3 to get 18.
Answer:
18
Explanation:
AB : DE = 5 : 15 5 ÷ 15 = 1/3
BC : EF = 8 : 24 8 ÷ 24 = 1/3
AC : DF = 6 : ? so 6 ÷ ? = 1/3
6 ÷ ? = 1/3
Multiply both sides by ?: 6 = (1/3)?
Multiply both sides by 3: 18 = ?
Therefore, the missing side = 18
