From the figure. a and b are equal because the lines are parallel. The jargon is alternate interior angles are equal.
The two remote interior angles are equal to the exterior angle. That interprets to
b + 2a = 84o But b = a
a + 2a = 84o
3a = 84
a = 84/3
a = 28 <<<< answer
b = 28 <<<< answer
2a = 56 <<<< answer.
        
             
        
        
        
Y = x + 14     (the larger bus has 14 more seats)
2x + y = 65       ( 2 x two times the seats , as it makes 2 trips the smaller van so the seats will be full twice maximum)
2x + x + 14 = 65   (sub the value of y = x+14 in the second equation)
3x = 51
x = 17 seat (smaller)
y = 31 seat (larger)

Answer:
CPCTC
Step-by-step explanation:
You already proved that triangle BAD is congruent to CAD, this means that all of the corresponding angles and sides with be congruent (CPCTC). That means BD is congruent to CD. Hope this helps!
