Answer: 11.56
Explanation:
LO bisects∠NLM,
LM=26, NO=8 and LN=18
We will use the angle bisector theorem
When a line bisects an angle, ratio of the two connecting sides with the angle that is bisected will be equal to the ratio of length of the segments whereby the angle bisector intersects the third side.
LN/LM = NO/OM
Let OM be represented by x
18/26 = 8/x
Cross multiply
18 × x = 26 × 8
18x = 208
x = 208/18
x = 11.56
OM = 11.56
