You notice a hot air balloon descending. The elevation h (in feet) of the balloon is modeled by the function h(x)=-12 x+300, where x is the time (in seconds) since you first noticed the hot air balloon.

Danny draws a transversal, t, on two parallel lines ab and cd, as shown below: he makes the following table to prove that the alternate interior angles are equal: which is the missing justification? (6 points) corresponding angles formed by a transversal on parallel lines are supplementary. corresponding angles formed by a transversal on parallel lines are congruent. co-interior angles formed by a transversal on parallel lines are congruent. co-exterior angles formed by a transversal on parallel lines are congruent.
