Answer:

Therefore, mCD = 113.6°

Explanation:

In the given triangle angle formed of the center will be defined by


sinx=(((36.7))/(2))/(21.8)


sinx=(18.35)/(21.8) = 0.8417

x =
sin^(-1)(0.842)

= 57.32°

Now angle formed at the center by CD will be = 2x ( 57.32 )

= 114.64°

Therefore, mCD = 113.6°
