Triangles ABC and DFG are similar.BWhich proportion can be used to find the value of DG?5 ft25 ftLA4 ft20 ft1BOсA7 ftG25DG=DGs tv20DG

When two triangles are similar their sides can be represented as ratios. This is the correct ratio for DG:
[tex]\frac{4}{20}=\frac{7}{DG}[/tex]The correct option is the second one.
