Complete the statement: If mangle upper G upper D upper F = 54º, then mangle upper E upper D upper F = ? . The drawing is not to scale.
Two adjacent triangles are shown.· Triangle upper D upper G upper F and triangle upper D upper E upper F have the shared side upper D upper F.
· Angle upper G upper D upper F and angle upper E upper D upper F are marked with a single angle arc.
· Angle upper D upper G upper F and angle upper D upper E upper F are marked with double angle arcs.
· Angle upper D upper F upper G and angle upper D upper F upper E are marked with triple angle arcs.
