Answer:

60°

Step-by-step explanation:

The radius of the circle is given as 7 ( centre of circle to point C )

The other radius is also 7 ( from centre to point D)

CD = 7

The triangle is therefore equilateral ( all 3 sides = 7 )

The angles of an equilateral triangle are equal and measure 60°

Hence mCD = 60°
