Answer:
1. Ans: mLABD = 110°
2. Ans: mLCBD = 65°
Step-by-step explanation:
1. Supplementary angles have a sum of 180°.
This would mean that when LABD and LCBD are added they will be equal to 180°.
Solve:
mLABD + mLCBD = 180°
mLABD + 70° = 180°
mLABD = 180° - 70°
mLABD = 110°
2. If mLABD = 115°
mLCBD + mLABD = 180°
mLCBD + 115° = 180°
mLCBD = 180° - 115°
mLCBD = 65°
