x =11
Explanation:
Scale factor : A scale factor is a number which multiplies of some quantity.
Given that
≅
![\triangle MNO](https://img.qammunity.org/2021/formulas/mathematics/middle-school/v3fnahes5pexffl42f544cllmx1w5pb20o.png)
SSS rule : If three sides of a triangle are congruent to the sides of another triangle. Then two triangle are congruent .
Since
and
congruent.
Then,
![(RS)/(MN) =(ST)/(NO) =(RT)/(MO)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/fq53qezoz8mc7o1bd994qwlro3teyqqn47.png)
Taking first two ratio
![(RS)/(MN) =(ST)/(NO)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/av3lbg48us4u0jahepofjrjms0gjb4xreh.png)
⇔
[ RS = 3 , ST= 5.5, MN= 6 and NO=x]
⇔3x =6×5.5
⇔
![x =(5.5 * 6)/(3)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/x2c1co14jjtgufqabfjc5q0xacivaw69y7.png)
⇔x =11
