Answer:
Option (a) is correct n = 3 and WX = 8
Step-by-step explanation:
It is given that, W lies in between X and Y. It means W is the mid point of X and Y. So,
XY = WX+WY .....(1)
We have, WX = 6n - 10, XY = 17, and WY= 3n
Putting the values in equation (1)
17 = 6n - 10 +3n
17 = 9n-10
Adding 10 both sides,
17+10 = 9n-10+10
27 = 9n
⇒ n = 3
We have, WX = 6n - 10
Put n = 3,
WX = 6(3) - 10
WX = 18-10 = 8
Hence, n = 3 and WX = 8
