Angular boe = 80
Because it should be an OD bisect AOC.
Because the angle BOE = 2 angle COE, the angle BOC = 3 angle COE, and because OD bisects the angle AOC, the angle AOC = 2 angle COD
Angular AOC = 180-angular BOC
So 2 angular COD = 180-angular BOC
1 3 angular boc (i.e. angular coe) + 1 2 (180-angular boc) = 70, so angular boc = 120
So the angle boe = 2 angle coe = 2 3 angle boc = 80

This problem can be solved as a binary equation. First of all, I don't understand the OD bisect angle BOC you said, is it the meaning of OD bisector AOC? If this is the case, then the angle AOD is of magnitude x and the angular eoc magnitude is y.
3y+2x=180, x+y=70, solution y=40, x=

It should be an OD rating AOC.
Let aod= cod=x; coe=y, then boe=2y is determined by a known condition:
x+y=70°
2x+3y=180°
Solution: x=30° y=40°
boe=2y=80°

Solution: AOC 60
BOC 180- AOC 180-60 120°OD bisect AOC
aod=1/2∠aoc=30°
aod+∠doe=90
aoe=∠aod+∠doe=90
aod=1/3∠aoe
aoe=3∠aod
3∠aod=90
aod=30
OD divides the AOC
aoc=2∠aod=60
coe=∠aoe-∠aoc=30

Because aod and doe are redundant, and aod=1 3 aoe, aod=2 doe
aod+ doe= aod+2 aod=3 aod=90°, so aod=30°

Solution: Let the degree of coe be x
Then the BOE power is 2X, and the AOC power is 180-3X, then the DOC power is.
doe=72°
i.e. doc+ coe=(
The solution is x=36°

It is known from foc=90°, Ranzhao 1=40°, 3=180°-90°-40°=50°
And since OE bisects AOD, and AOD+ 3=180°, the key 2=(180°- 3) 2=65°

cd = 4 cm, so cd does not coincide with the celebration of the potato. So, point C and point D are between AB and point D and point BA extension. (otherwise coincide) let the chain between the positive ab is, so da=(5 4)aba=ac+bc=ac+(9 5)ac=(14 5)ac, so the honorable ac=(5 14)abcd=da+ac=(5 4)ab+(5 14)ab=(45...).
