Determine the value of angle LJM if the measure of KJM is 6x and the measure of LJK is 4x + 12




Given the problem, we have the following information:

- The measure of angle \( \angle KJM = 6x \).
- The measure of angle \( \angle LJK = 4x + 12 \).

The angle \( \angle LJM \) is composed of the sum of \( \angle LJK \) and \( \angle KJM \), because the points \( L \), \( K \), and \( M \) are on rays extending from the common vertex \( J \).

### Step-by-Step Solution:

1. **Determine \( \angle LJM \) as a sum of the given angles:**
   \[
   \angle LJM = \angle LJK + \angle KJM
   \]

2. **Substitute the given expressions:**
   \[
   \angle LJM = (4x + 12) + (6x)
   \]

3. **Simplify the expression:**
   \[
   \angle LJM = 4x + 6x + 12 = 10x + 12
   \]

Thus, the measure of \( \angle LJM \) is \( 10x + 12 \) degrees.

### Conclusion:
The value of \( \angle LJM \) in terms of \( x \) is \( 10x + 12 \) degrees.
