The measure of ED from the figure is 12 units
Similarity theorem of triangles
From the given figure, the expression below is true;
AE/AB = ED/CD
Substitute the sides
2x+4/9 = x +4/6
6(2x+4)= 9(x+4)
12x + 24 = 9x +36
3x = 12
x = 4
Determine ED
ED = 2x +4
ED = 2(4) + 4
ED =12 units
Hence the measure of ED from the figure is 12 units
