Answer:

$\frac{3x - 2}{2} = 5 \\ multipy \: both \: side \: by \: 2\\ \frac{3x - 2}{2} \times 2 = 5 \times 2 \\ 3x - 2 = 10 \\ add \: 2 \: to \: both \: side \\ 3x - 2 + 2 = 10 + 2 \\ 3x - 0 = 12 \\ 3x = 12 \\ divide \: both \: side \: \frac{3x}{3} = \frac{12}{3} \\ x = 4$

Given ZW=20. Answer the questions please.

djyliett [7]

a) Corresponding angles of similar figures are congruent, so $\angle B \cong \boxed{\angle Z}$

b) Scale factor = (image)/(preimage). Since we are looking for ABCD to WZYX, this means that WZYX is the image and ABCD is the preimage. Thus, the scale factor is $\frac{25}{10}=\boxed{5/2}$

c) Since the scale factor is 5/2,

$\frac{20}{t}=\frac{5}[2}\\\\40=5t\\ \\ t=\boxed{8}$
