Answer:
- B. BC = 18 so ∆ABC ～ ∆DEF by SAS
Step-by-step explanation:
[tex] \bf \cfrac{AB}{DE} = \cfrac{BC}{EF} [/tex]
- [tex] \bf \cfrac{15}{10} = \cfrac{BC}{12} [/tex]
- [tex]\bf \cfrac{3}{2} = \cfrac{BC}{12} [/tex]
- [tex]\bf BC = \cfrac{3}{2} \times 12 [/tex]
- [tex]\bf 3 \times 6[/tex]
- [tex]\bf BC = 18[/tex]
- [tex] \bf \angle B = \angle \: E[/tex]
So, ∆ABC ～ ∆DEF by SAS.
