Answer:

arc ed is 38 degrees

Step-by-step explanation:

dc is 90
bc is 52
ad is 180
90 + 52 = 142
180 - 142 = 38
ab (38) is the same as ed
ab = ed
ed = 38

Answer:

142

Step-by-step explanation:

the whole circle is 360 degrees.

90+52=142

180-142=38

AB=38 is the same as DE.

90+52+38+38=218

360-218=142.
