Answer:

x = 4

Step-by-step explanation:

The sum of interior angles in a triangle is equal to 180

72 + 51 + 13x + 5 = 180 add like terms

128 + 13x = 180 subtract 128 from both sides

13x = 52 divide both sides by 13

x = 4

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.
