Question

Please help quick
If these triangles are similar, what is the length of side DF?

Answer 1

✿
`\mathsf{Scale\;Factor = (1.5)/(2.5) = (15)/(25) = (3)/(5)}`

`\mathsf{\implies Length\;of\;DF = (3)/(5) * AC}`

`\mathsf{\implies Length\;of\;DF = (3)/(5) * 4}`

`\mathsf{\implies Length\;of\;DF = (0.6)(4)}`

`\mathsf{\implies Length\;of\;DF = 2.4\;u}`
