Question

in the given figure AB parallel to CD parallel to EF the value of (y+x):(y-x) is

Answer 1

Answer:

given-

AB//CD

CD//EF

in // line AB and CD let PR the transversal

∠BPR + ∠DRP=1800 (co-interior ∠)

500 + y= 1800

y=1800-500

y=1300

now in // Lines CD and EF let ST the transversal

∠DST=∠ETS

1100=∠ETS

∠ETS=300+x

1100-300=x

x=800

y-x

y+x

=1300-800

1300+800

=500/2100

=5:21
