Answer:

coa=90

cob=23

bda=274

ea=90

abe=157

de=90

ce=180

Step-by-step explanation:

for coa it's a 90 dagree angle  

for cob= it's 23 90-67=23

for bda= you take the half and see that it's 180 so you add 180 and 67 and get 274 because a whole circle is 360degrees

for ea again it's 90 degrees

for abe it's the 180 again

for de it's the 90 again

for ce it's just half a circle so it's 180
