Angle DHE and angle EHF are supplementary What is the measure of angle FHG See picture for the angles class=

Respuesta :

11x + 7x = 18x
18x = 180
X = 10
FHG = 70°
11x+7x=180
18x=180
x=180/18
x=10

∠ DHE=7x=7•10=70 degrees

∠EHF=11x=11•10=110 degrees

∠FHG=y
11x+y=180
11•10+y=180
110+y=180
y=180-110
y=70

∠FHG=180
