Answer:

Since GI bisects that means the angle is cut into 2 equal angles or

DGI = IGH

So

x - 3 = 2x - 13

Solve for x

13 - 3 = 2x - x

10 = x

x = 10

Answer:

[tex]3x - 9 = 2x + 21 \\ 3x - 2x - 9 = 2x - 2x + 21 \\ x - 9 = 21 \\ x - 9 + 9 = 21 + 9 \\ x = 30[/tex]

m<DGI = 80°

[tex]3x - 9 = \\ 3(30) - 9 = \\ 90 - 9 = 81[/tex]
