Answer:
40 m
Explanation:
Given midline JK = (6x -4) m and baseline HG = 10x m, you want the measure of HG.
Midline
The midline of a triangle is half the length of the parallel baseline.
JK = 1/2·HG
6x -4 = 1/2(10x)
x -4 = 0 . . . . . . . . . subtract 5x
x = 4
10x = 10·4 = 40
The measure of HG is 40 meters.
