In the right triangle shown, \angle A = 30^\circ∠A=30 ∘ angle, A, equals, 30, degrees and AC = 6AC=6A, C, equals, 6. How long is ABABA, B? Answer exactly, using a radical if needed.

Match the following reasons with the statements given to create the proof. 1. do = ob, ao = oc sas 2. doc = aob given 3. triangle cod congruent to triangle aob vertical angles are equal. 4. 1 = 2, ab = dc if two sides = and ||, then a parallelogram. 5. ab||dc if alternate interior angles =, then lines parallel. 6. abcd is a parallelogram cpcte
