Answer: Your answer is D
Explanation:
To start, angle ACD is an obtuse angle, so we can eliminate answers A and B.
Now we need to find angle C of triangle ABC. A triangle has a total of 180 degrees, so we can just add angles A and B then subtract that from 180 to find angle C.
117+33=150. 180-150=30 So we now know that angle C of triangle ABC is 30 degrees. We also know that a strait line is 180 degrees, so the angle of BCD is 180. to find angle ACD we need to subtract angle C of triangle ABC from angle BCD.
180-30=150. So we now know that angle ACD is equal to 150 degrees.
