Answer:

The correct answer is option  C - 40°

Step-by-step explanation:

From the figure we can see a circle.

CD and CE are the two tangents from a common external point C.

CD = CE

To find the measure of <DCE

Consider the quadrilateral <DAE.

<D = <E = 90°  [ Angles made with tangent and radius]

m<DCE + m<DAE = 180°

m<DCE = 180- m<DAE

 = 180 - 140

 = 40°

The correct answer is option  C - 40°
