Answer:
A. is not true
Step-by-step explanation:
[tex]\angle{BCA}[/tex] appears to be acute, and [tex]\angle{BCD}[/tex] appears to be its obtuse supplement.
Just to be sure the diagram isn't lying to you, set this up:
4x + 9 + (9x - 11) = 180
13x - 2 = 180
13x = 182
x = 14
[tex]m\angle{BCA}=65^\circ\\m\angle{BCD}=115^\circ[/tex]
Those two angles are not congruent.
