Use the diagram for Items 1–2.
1. Given that mABD = 16°, find mABC.
2. Given that mABD = (2x + 12)° and mCBD = (6x – 18)°, find mABC.
32°
54°

8.6
Use the diagram for Items 3–4.
3. Given that FH is the perpendicular bisector of EG, EF = 4y – 3, and FG = 6y – 37, find FG.
4. Given that EF = 10.6, EH = 4.3, and FG = 10.6, find EG.
