Answer:
mCD=77°
Step-by-step explanation:
-The measure of the arc angle subtending from the diameter adds up to 180° .
-Given mAD=(19x – 49)° and mCD = (5x + 37)°, we equate their sums to 180° and solve for x:
[tex]mAD+mCD=180\textdegree\\\\\\(19x-49)\textdegree+(5x+37)\textdegree=180\textdegree\\\\\\24x=192\textdegree\\\\x=8\textdegree\\\\\\\therefore mCD=(5x+37)\textegree=(5\times8+37)\textdegree\\\\\\=77\textdegree[/tex]
Hence, mCD=77°
