Answer:
The measurement of angle JKL is x
Explanation:
The angle bisector of KE tells you that the two angles on either side of that line are equal.
If we take the measurement of the big angle and subtract out the little angle that we know, we will find the measurement of the angle we are looking for.
4x + 6 - (3x +6)
4x + 6 - 3x -6
x
