a) Identify the quadrilateral Explain your reasoning. b) If m2B = 75°, find m2D. Explain your reasoning.
A) The quadrilateral is a trapezoid because it has 2 parallel sides
B) Given that AC and DB are parallel, and AB and CD are congruent, then ∠B and ∠D are congruent too. This means that m∠D = 75°
