Use the square DEFG to find the following:

HF=_
GE=_
GF=_
m<GHF=_
m<DEF=_
m<DGH=_

The answer to your question is below

Step-by-step explanation:

HF = HE = 5

GE = 2HE = 2(5) = 10

GF = EF = 7.1

m∠GHF = 90°   because m∠HGF = 45° and m∠HFG = 45° and  

                          the sum of the internal angles in a triangle equals 180°.

m∠DEF = 90°   the sum of the internal angles in a square equals 360°

                         then, 360/4 = 90°.

m∠DGH = 45°  because the angle ∠DGF was cut in two equal angles.

i believe the answer is letter c) 8
