Solve (x+2< 5)∩(x-7> -6)

a.) {x|1
b.) {x|x< 3 or x> 1} (it said that this one was wrong so there's some on my behalf.)

c.) {all real numbers}

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
