In the figure, ΔABC ~ ΔDEF. Solve for x. Triangles ABC and DEF. Angles B and E are congruent and measure 160 degrees. AB measures x. BC measures 16. DE measures 3. EF measures 8. x = 1.5 x = 6 x = 4 x = 5.5

1.5 is what i got

k..

5. DanJS

~ means similar right..

6. anonymous

ya

7. DanJS

ok i think you mixed it up a bit...

8. anonymous

how

9. DanJS

since the triangles are similar, the ratios of similar sides are the same...

10. anonymous

so that means it would have to be 5.5

11. DanJS

$\frac{ DE }{ AB } = \frac{ EF }{ BC }$

12. anonymous

so i was right because it would equal and 5.5 shows that

13. DanJS

$\frac{ 3 }{ x } = \frac{ 8 }{ 16 }$

14. anonymous

im lost

15. DanJS

the ratios of DE/AB has to be the same as EF/BC , since they are similar triangles

16. DanJS

just have to fill in the numbers

17. anonymous

well now i got 6 i multiplied then divided by 100

18. DanJS

yep, x=6

19. anonymous

yesss

20. anonymous

thats cross multiplying

21. anonymous

thank you
