4)75°
5)65°
6)115°
7)100°
8)105°
9)70°

hope it helps

Answer 2

angle AGF=45+30-180
=105

angle DGE=105 because vertically opposite angle

angle AGD=180-105 because linear pair
=75

angle EGF=75 because vertically opposite angle

angle DEG=35 because angle sum property



angle GEC= 145 because linear pair


angle GFC=100 because linear pair



angle CBF=105 because angle sum property



angle ECF=40 because sum of all angles in a quadrilateral is 360
