Two similar polygons are shown below. Find the value of x and y.

x = 18, y = 12

Step-by-step explanation:

Δ SRT and Δ VUT are similar then the ratios of corresponding sides are equal, that is

= , substitute values

= ( cross- multiply )

4x = 72 ( divide both sides by 4 )

x = 18

From side ST

y + 6 = 18 ( subtract 6 from both sides )

y = 12

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
