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

ok i think you mixed it up a bit...
anonymous
  • anonymous
how
DanJS
  • DanJS
since the triangles are similar, the ratios of similar sides are the same...

  • anonymous
so that means it would have to be 5.5
DanJS

\[\frac{ DE }{ AB } = \frac{ EF }{ BC }\]

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

\[\frac{ 3 }{ x } = \frac{ 8 }{ 16 }\]

im lost
DanJS
  • DanJS
the ratios of DE/AB has to be the same as EF/BC , since they are similar triangles
DanJS
  • DanJS
just have to fill in the numbers
