Use the note that Linear pairs have sum 180°

  • TD is a straight line


\\ \rm\rightarrowtail m\overset{\frown}{CD}+122=180


\\ \rm\rightarrowtail m\overset{\frown}{CD}=180-122=58°

Now

  • DB arc be x

  • A whole angle is 360° or 2π


\\ \rm\rightarrowtail x+122+58+90=360


\\ \rm\rightarrowtail x+270=360


\\ \rm\rightarrowtail m\overset{\frown}{DB}=90°
