The calculated length of the segment JM is 40 units
How to determine the length of JM
From the question, we have the following parameters that can be used in our computation:
The line segment
Where, we have
JM = MK
Substitute the known values into the equation
7x + 5 = 8x
Evaluate
x= 5
So, we have
JM = 7 * 5 + 5
Evaluate
JM = 40
Hence, the length of JM is 40 units
