Question

In (circle)A, m∠BAD = 110. Find mDE.

Answer 1

Answer: 70 degrees

Reason:

Central angle BAD is 110 degrees.

This makes angle DAE to be 180-110 = 70 degrees since the two angles are supplementary. They combine to a 180 degree straight angle.

From there, minor arc DE is also 70 degrees. This is because the central angle subtending the arc will be the same measure.

Answer 2

Answer: 70

Step-by-step explanation: BAD is 110 degrees and BDE is 180 so do 180 minus 110 and gets you 70 which is DE
