What is the measure of de?

51
56
68
85

Option 3 is right

68 is the answer.

Step-by-step explanation:

Given is a circle with some points A, B, C, D and E

We have to find measure of arc DE

We find that angle of arc DE = angle DOE

and angle of arc DC = DOC =112

DOE and DOC are supplementary angles since they form a linear pair on the straight line EOC

Hence angle DOE = 180-112 = 68

Thus angle of arc DE is the angle that DE subtends at the centre of circle =

DOE = 68

Option 3 is correct

answer: the area of the parallelogram below is 42 square meters.
