= 216
Answer:
x=0
Step-by-step explanation:
letter B
Look at the picture.
1)|AM| = |MB| = x
|AN| = |NC| = y
|BC| = 2y - 2x = 2(y - x)
|MN| = y - x
Therefore |BC| = 2|MN|
2)|AM| = |MB| = x
|AN| = |NC| = y
|BC| = 2y - 2x = 2(y - x)
|MN| = y - x
Therefore |BC| = 2|MN|
Answer:
![KS = 12](https://tex.z-dn.net/?f=%20KS%20%3D%2012%20)
Step-by-step explanation:
Given that ∆KLM ~ ∆RSK,
(similarity theorem)
KL = 65
KR = 65 - 52 = 13
KM = 60
KS = ?
![\frac{65}{13} = \frac{60}{KS}](https://tex.z-dn.net/?f=%20%5Cfrac%7B65%7D%7B13%7D%20%3D%20%5Cfrac%7B60%7D%7BKS%7D%20)
Cross multiply
![65*KS = 60*13](https://tex.z-dn.net/?f=%2065%2AKS%20%3D%2060%2A13%20)
![65*KS = 780](https://tex.z-dn.net/?f=%2065%2AKS%20%3D%20780%20)
![\frac{65*KS}{65} = \frac{780}{65}](https://tex.z-dn.net/?f=%20%5Cfrac%7B65%2AKS%7D%7B65%7D%20%3D%20%5Cfrac%7B780%7D%7B65%7D%20)
![KS = 12](https://tex.z-dn.net/?f=%20KS%20%3D%2012%20)
