Answer 2

Answer:

100 degrees

Step-by-step explanation:

The three angles inside a triangle always add up to 180

so, 180-43-57 is 80

But that's the angle inside the triangle. notice that that angle (ACD) and BCA make a straight line.  That means they add up to 180. Therefore, 180-80=100 degrees.
