If KM bisects angle JKL, JKL=92 degrees, and MKL=(5x+1) degrees, find the value of x

To solve for \( x \) given that \( KM \) bisects angle \( JKL \), \( \angle JKL = 92^\circ \), and \( \angle MKL = (5x + 1)^\circ \), follow these steps:

1. Since \( KM \) bisects \( \angle JKL \), it divides \( \angle JKL \) into two equal angles:
   \[
   \angle JKM = \angle MKL
   \]

2. Therefore, each of these angles is half of \( \angle JKL \):
   \[
   \angle JKM = \angle MKL = \frac{1}{2} \times 92^\circ = 46^\circ
   \]

3. Given that \( \angle MKL = (5x + 1)^\circ \):
   \[
   5x + 1 = 46
   \]

4. Solve for \( x \):
   \[
   5x + 1 = 46
   \]
   \[
   5x = 46 - 1
   \]
   \[
   5x = 45
   \]
   \[
   x = \frac{45}{5}
   \]
   \[
   x = 9
   \]

Thus, the value of \( x \) is \( 9 \).
