In the figure, △ABC ~ △DEF. Solve for x x = 2.2 x = 16.36 x = 55 x = 66

OpenStudy (anonymous):

ok the same rule applies here triangle ABC is proportional to triangle DEF

OpenStudy (anonymous):

so that means side ED/EF is proportional to BA/AC

OpenStudy (anonymous):

ED/EF = 6/11 so BA/AC has to equal 6/11 as well

OpenStudy (anonymous):

what what value of 30/x = 6/11?

OpenStudy (anonymous):

so it would be 55?

OpenStudy (anonymous):

correct

OpenStudy (anonymous):

In the figure, △ABC ~ △GFE, ∡ABD ≅ ∡DBC, and ∡GFH ≅∡HFE. Solve for x. x = 4 1/4 x = 111/4 x = 18 x = 9/10

OpenStudy (anonymous):

i got comfused with the multiple letters and numbers could you help me?

OpenStudy (anonymous):
