Answer:
3
Step-by-step explanation:
The question is incomplete. Here is the correct question.
If NL = 13, find NM. NM = X+15 ML = 2x+34
Using vector notation, NL = NM+ML
Substituting the given parameters into the equation;
13 = x+15+(2x+34)
13 = x+15+2x+34
Collect like terms.
x+2x+15+34 = 13
3x+49 = 13
3x = 13-49
3x = -36
x = -12
Given NM = x+15 and x = -12
NM = -12+15
NM = 3
