Answer 1

GH ≈ 6.0

Explanation:

since the triangles are similar then the ratios of corresponding sides are in proportion, that is

`(GH)/(DE)` =
`(HI)/(EF)` ( substitute values )

`(GH)/(34)` =
`(8)/(45)` ( cross- multiply )

45 GH = 34 × 8 = 272 ( divide both sides by 45 )

GH ≈ 6.0 ( to the nearest tenth )
