Step-by-step explanation:

4

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

= ( substitute in values )

= ( 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

= ( cross- multiply )

10y = 24 ( divide both sides by 10 )

y = 2.4
