50 Points, 5 stars, and Brainliest Answer for the BEST Answers! Your answers MUST be correct, and you must answer them ALL!
devlian [24]

#1:Proportional Medians Theorem


#2:BD/FH = CB/GF


#3: 24/16 27/x


So the first ratio is 3/2 because both are divisible by 8. the ratio stays 3/2. 3*9=27. so 2*9=18


x=18


#4: x = 8.5

#5: x = 68


Hope this helps!!
