∆ABC ~∆DEF so if BC=8 , EF=24 and DE=21, then AB=____?____ ( THERE ARE 2 ANSWERS)
Accepted Solution
A:
Let's look at the difference between BC and EF.
24:8
Simplify it.
3:1 It was dilated by 3.
So, we just need to divide 21 by 3.
21/3= 7
AB= 7
I don't understand why there are two answers to the question because the question is specifically asking for what is equal to AB. It might be asking you to tell them what is congruent to AB, in that case; DE is congruent to AB.
