Answer:
The answer to your question is number 3. 15.5
Step-by-step explanation:
Solve this problem using proportions
Equation
[tex]\frac{JK}{MK} = \frac{KL}{KN}[/tex]
Substitution
[tex]\frac{10 + 4}{4} = \frac{7 + x + 2}{7}[/tex]
[tex]\frac{14}{4} = \frac{9 + x}{7}[/tex]
7(14) = 4(9 + x)
98 = 36 + 4x
4x = 98 - 36
4x = 62
x = 62 / 4
x = 15.5
