Step-by-step explanation:
Answer:
Explanation:
First you need to factor out the GCF (greatest common factor) of the numbers, which is 8n.
The GCF cancels out on top and bottom so it becomes:
180 = 72 + (2x) + x
subtract 72 from both sides.
108 = 3x
divide both sides by 3.
36 = x
m<DEF = 72*
m<EFD = 72*
m<EDF = 36*
M<FDG = 36 / 2 = 18 <<<<<<<
