Question

Helpppppppppppppppppppp pleaseeeeeeeeeee

Answer 1

FG = 16

Explanation:

if df bisects <edg then triangles DFE and DFG are similar AAA

since DF is the same in both triangles triangles DFE and DFG are congruent

therefore FE = FG

n+5 = 2n-6

subtract n from each side

n-n+5 = 2n-6-n

5 = n-6

add 6 to each side

5+6 = n

n=11

FG = 2n-6

=2*11 -6

= 22-6

= 16
