So we already know that a triangle's angles sum up to 180 correct?

So what you want to do is use the given angle 114 to find Angle ACD.

What you do is do 180-114 and you get 66 which is the angles for ACB

and then you do \(66+66+66-x=180\)

\(198-x=180\)

\(x= 18\)

\(66-18=48\)

\(\angle ACD = 48°\)

The answer is actually 18 Degrees since we have to find ACD, not DCB. Thanks for the answer though :)

Notice that triangle CDB is isoceles, with DB being the base. And ABC is isoceles.

I can assume you can use your knowledge on isoceles triangles and straight angles to figure out the answer.
