Answer 1

Answer:

see explanation

Step-by-step explanation:

4

Since the triangles are similar then the ratios of corresponding sides are equal, that is

$\frac{BC}{EF}$ = $\frac{AB}{DE}$ ( substitute in values )

$\frac{x-1}{18}$ = $\frac{4}{12}$ ( cross- multiply )

12(x - 1) = 72 ( divide both sides by 12 )

x - 1 = 6 ( add 1 to both sides )

x = 7

The parallel line segment SV is half of RW

that is x = 7.5

SV also divides the sides RT and WT in proportion, that is

$\frac{10}{3}$ = $\frac{8}{y}$ ( cross- multiply )

10y = 24 ( divide both sides by 10 )

y = 2.4
