Hello there,
The first thing to take into account is:
“EF bisects CD”.
In geometry, “bisects” means to dive into two exactly equal parts.
If EF bisects CD on G, CG measures the same as GD
CG = GD
5x - 1 = 7x - 13
12 = 2x
6 = x
Now you know the value of “x”.
If EF = 6x - 4 and x = 6, EF = 6*6-4 =32
EF = EG + GF
32 = EG + 13
So, EG = 19
Kind regards,
Daniela
