Answer:

y = 3

Step-by-step explanation:

The figures are similar so the ratios of corresponding sides are equal, that is

\frac{UR}{DA} = \frac{TS}{CB} , substitute values

\frac{4}{2} = \frac{3y+5}{7} ( cross- multiply )

2(3y + 5) = 28 ( divide both sides by 2 )

3y + 5 = 14 ( subtract 5 from both sides )

3y = 9 ( divide both sides by 3 )

y = 3
