Answer:

AE = minor arc = 144°

BC = minor arc = 43°

AC = minor arc = 110°

ACD = semi circle = 180°

ACE = major arc = 216°

DEC = major arc = 290°

Explanation:

Minor arc are arc not up to half of the revolution of one circle i.e not up to 189° while major arc are the ones more than 180°.

Semici circle has it's angle = 180°.

AE = 360 - ( ED+AD)

AE = 360-(36+180)

AE = 360 - 216

AE = 144°

BC = 180 - ( AB+ CD)

BC = 180 - (67+70)

BC = 180 - 137

BC = 43°

AC = AB + BC

AC = 67 + 43

AC = 110°

ACD = SEMI CIRCLE

ACD = 180°

ACE = 360- AE

ACE = 360- 144

ACE = 216

DEC = 360 - 70

DEC. = 290°
