Question

The polygons in each pair are similar. Find the missing side length.

Answer 1

Let missing one be x

If both are similar

`\\ \sf\longmapsto (20)/(25)=(16)/(x)`

`\\ \sf\longmapsto (4)/(5)=(16)/(x)`

`\\ \sf\longmapsto 4x=16(5)`

`\\ \sf\longmapsto x=(16(5))/(4)`

`\\ \sf\longmapsto x=20`
