Question

Help !!!!!

Answer 1

they are similar triangles so their sides are proportional by the same ratio.

so 4 : 6 has the same ration as n : 4.5 and as 5: m

this can be setup as

\[\frac{ 4 }{ 6 } = \frac{ n }{ 4.5 } = \frac{ 5 }{ m }\]

Answer 2

so do i cross multiply

Answer 3

yes. once for m and again for n
