![\boxed{x = 7}](https://img.qammunity.org/2021/formulas/mathematics/college/ejlbfslimckmpzs0pajswv890dbudaaa56.png)
Explanation:
ΔJKL ~ ΔMNP
So, the sides of both of the triangles are proportional.
Taking proportionality of their sides.
![(JL)/(JK) = (MP)/(MN)](https://img.qammunity.org/2021/formulas/mathematics/college/hiog36ezh1oayv22ssyotj1a6vbeyn1z1d.png)
=>
![(20)/(25) = (4x-4)/(30)](https://img.qammunity.org/2021/formulas/mathematics/college/c19cw9ofpc7db019a802bhnqbc3n8it9mp.png)
Cross Multiplying
20 * 30 = 25(4x-4)
600 = 100x - 100
Adding 100 to both sides
600+100 = 120x
700 = 100x
Dividing both sides by 100
700/100 = x
x = 7
