A. In OEAB, AC, AD,CD, and are chords. Use the figure and the given information to answer the following questions. o 1. IMZADB = 40", what ismAB? 2. If mLBAC = 30°, what ismBC? 3. If mBC = 50°, what ism2BDC? 4. If mAD = 120, what ismLABD? 5. If mLABD = 44, what ismLACD? 6. What is the value of xif LACD = 70' and AD= (5x-20) F B B. Complete the two-column proof of the theorem which states that "If two inscribed angles of a circle (or congruent circles) intercept congruent arcs or the same arc, then the angles are congruent." Q B Given: In OT, PR is the intercepted arc of ZPQR and AC is the intercepted arc of LABC, W PR AC R с Prove. ZPOR LABC р
