The value of x is 299
Step-by-step explanation:
It is given that
![RSTU\sim WXYZ](https://img.qammunity.org/2021/formulas/mathematics/middle-school/xeksqcuso6t99octvzklruu707vimus86h.png)
Since, the two trapezoids are similar, their corresponding sides of the two trapezoids are proportional.
Thus, we have,
![(RS)/(WX)=(ST)/(XY)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/bxbzwnszqbku5kfd9kddivvj7x58jwmebk.png)
Substituting the values of these sides, from the figure, we get,
![(391)/(170)=(x)/(130)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/mquof4v2hvq1teri0n5einsxvw5r0t8p18.png)
Multiplying both sides by 130, we get,
![((130)391)/(170)=x](https://img.qammunity.org/2021/formulas/mathematics/middle-school/4ybvpmi0e6blb01mj33lj0hhzpco8iu3jg.png)
Multiplying the numerator, we get,
![(50830)/(170) =x](https://img.qammunity.org/2021/formulas/mathematics/middle-school/xlv2q9aglvrva02340bjz6e8bc9dh5b7ib.png)
Dividing, we have,
![299=x](https://img.qammunity.org/2021/formulas/mathematics/middle-school/3vogcrigklolbn1f9yxol4yevyb8433yai.png)
Thus, the value of x is 299.
