The value of x is 299

Step-by-step explanation:

It is given that
RSTU\sim WXYZ

Since, the two trapezoids are similar, their corresponding sides of the two trapezoids are proportional.

Thus, we have,


(RS)/(WX)=(ST)/(XY)

Substituting the values of these sides, from the figure, we get,


(391)/(170)=(x)/(130)

Multiplying both sides by 130, we get,


((130)391)/(170)=x

Multiplying the numerator, we get,


(50830)/(170) =x

Dividing, we have,


299=x

Thus, the value of x is 299.
