Answer:
The statement is mABC=26
The reason is mABC+mCBD=52
Explanation:
The statement should be mABC=26, that is what you are supposed to be proving.
The reason should be mABC+mCBD=52, because the given was that mABD was 52, therefore, if mABC is 26, and BC bisects mABD (meaning it’s divided into two equal parts), the other angle should be 26 as well. 26+26=52.
