Answer:
x = 4.5
Step-by-step explanation:
The attached figure shows the diagram of this problem. Here, line m is intersected by line l and m. We need to find the value of x.
In this case, 6x+42 =18x-12 as they form alternate interior angles
So,
6x+42 =18x-12
taking like terms togther
6x-18x=-42-12
-12x = -54
x = 4.5
So, the value of x is 4.5
