P=(8,7,6,5) q= 1,2,3,4, 12, 3,4,1,2,1,14,13 referring to the two following matrices

Which of the following is the shape of a cross section of the figure shown below

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.

This is about circle theorems. someone asap : (
