Answer:
34/39
Step-by-step explanation:
scale factor = new length / old length
34's factors are 1, 2, 17, 34
39's factors are 1, 3, 13, 39
no common factors bigger than 1 so cannot simplify
140
you would find the perimeter 8+8+6+6=28, then you multiply it by the height so it would be 28x5=140
I am not sure it is 2i think
SSS congruency criteria can be used here to prove ∆ABC ≅ ∆DCB
In ∆ABC and ∆DCB
AB = CD (given)
AC = BD (given)
BC = BC (common)
So, by SSS congruency criteria,
∆ABC ≅ ∆DCB
