The measure of the side MK is equivalent to 4
The given diagram is. a triangle with the side JK similar to JL
Since JK = 6x + 1 and JL = 10x - 17 and JK = JL, hence:
6x + 1 = 10x - 17
6x - 10x = -17 - 1
-4x = -18
x = 18/4
x = 4.5
For the length of MK
MK = 2x - 5
MK = 2(4.5) - 5
MK = 9 - 4
MK = 4
Hence the measure of the side MK is equivalent to 4
