Question

Please explain hot to find length KC on the attached diagram. Thanks!

Answer 1

KC=54

Explanation:

You have the number for MU=78, HU=96

so that you can find HM=HU-MU=96-78=18

and then JH=22, JK=82 and we got HM=18

so that you can find MK=JK-JH-HM=82-22-18=42

And then MU=78,

so KU=MU-MK=78-42=36

And then CN=51, KN=105 and we just got KU=36,

so UC=KN-CN-KU=105-51-36=18

And you want to find out what's the length of KC,

KC=KU+UC=36+18=54

So your final answer is KC=54.

Answer 2

The correct answer is KC = 54

Explanation:

From the given figure we can see that,

total length JN = 82 + 105 = 187

To find the length KC

From figure we can write,

KC = Total length - (JK + CN) = JN - (JK + CN)

JN = 187

JK =82 and CN = 51

Therefore KC = 187 - (82 + 51) = 187 - 133 = 54

The correct answer is KC = 54
