Answer 1

bt where is the figure

Answer 2

Answer:

Step-by-step explanation:

Our question is: In the figure, o is the centre of the circle and angle abc=100° cd=de. Find angle cde.

Let d be the angle we are looking for.

Since both angles ∠ABC and ∠CDE are opposite angles, we can conclude that it is a fact that they must be supplementary in order to the sum of the angles be correct.

Hence, we conclude that in order to get the best answer, our angle ∠CDE is equal to 80 degrees.
