Hey!
On the small triangle, the length is 3. On the bigger triangle, the length is 6.
Scale Factor:
[tex] 3 \times x = 6 [/tex]
[tex] 6 \div 3 = 2 \\ x = 2 [/tex]
The scale factor is 2
[tex] \framebox{Scale Factor = 2} [/tex]
[tex] x = 5.5 \times 2 \\ 5.5 \times 2 = 11 \\ [/tex]
x is equal to 11
[tex] \framebox{x = 11} [/tex]
