Solve for x the triangles In Each pair LMN~LRS <br> Please help quickly and show work pleasee
Gala2k [10]

Given:

\Delta LMN\sim \Delta LRS

To find:

The value of x.

Solution:

We have,

\Delta LMN\sim \Delta LRS

We know that the corresponding sides of similar triangles are proportional. So,

\dfrac{LM}{LR}=\dfrac{LN}{LS}

\dfrac{18}{2x-18}=\dfrac{30}{10}

\dfrac{18}{2x-18}=3

18=3(2x-18)

Using distributive property, we get

18=3(2x)-3(18)

18=6x-54

18+54=6x

72=6x

Divide both sides by 6.

\dfrac{72}{6}=x

12=x

Therefore, the correct option is A.
