9. A model airplane takes off at a constant rate of 15 feet per second. Its height, in feet, after t seconds is given by h = 15t. At the same time, a
ball is launched from ground level with an initial velocity of 45 feet per
second. The height of the ball, in feet, after t seconds is given by
h=-16t? + 45t. Will the airplane and ball collide? If so, find the time it
takes for the collision to occur.

Given: ae ≅ ce ; de ≅ be prove: abcd is a parallelogram. we have that ab || dc. by a similar argument used to prove that △aeb ≅ △ced, we can show that △ ≅ △ceb by. so, ∠cad ≅ ∠ by cpctc. therefore, ad || bc by the converse of the theorem. since both pair of opposite sides are parallel, quadrilateral abcd is a parallelogram.
