Answer 1

Answer: 236 degrees

Step-by-step explanation: Add the two angles that are given. 44+80=124. The angle DOB is 124 degrees. The angle DEB is the rest of the circle. There are 360 degrees in a circle. So subtext 360 from 124.

360 - 124 = 236

DEB = 236 degrees.

Answer 2

m<DEB = 62°

Explanation:

From the figure we can see a circle with center O.

To find the measure of <DOB

From the figure we get,

m<DOC = 44° and m<COB = 80°

We know that, m<DEB = m<DOB/2

m<DOB = m<DOC +m<COB

= 44 + 80

= 124

To find the measure of <DEB

m<DOB = 124

Therefore m<DEB = m<DOB/2

= 124/2 = 62°
