Question

Please help:
given WXYZ is similar to RSTV. find ST​

Answer 1

ST = 13.5

Explanation:

since the figures are similar then the ratios of corresponding sides are in proportion , that is

`(ST)/(XY)` =
`(RS)/(WX)` ( substitute values )

`(ST)/(9)` =
`(18)/(12)` ( cross- multiply )

12ST = 9 × 18 = 162 ( divide both sides by 12 )

ST = 13.5
