Question

if line r bisects DG at point E, and if DE= 2z +2 and DG = 5z-7, then find DG

Answer 1

Answer:

DG = 48

Step-by-step explanation:

if line r bisects DG at point E, then point E is midpoint of DG

so DG = 2DE

5z - 7 = 2(2z + 2)

5z - 7 = 4z + 4

5z -  4z = 4 + 7

z = 11

DG = 5z - 7 = 5(11) - 7 = 55 - 7 = 48
