In the figure below DA is a diameter of the circle ABCDE centre O, radius 10cm. AB=BC and angle DAC= 36⁰

In the figure below DA is a diameter of the circle ABCDE centre O, radius 10cm. AB=BC and angle DAC= 36⁰

Giving reasons, find the size of the angle;
(i) CDB;
(ii) DBC
(iii) DOC
(iv) OCA
(v) DEB

---

i) COB = 27⁰
(angle substained by Same arc)
ii) DBC= 36⁰
(angle subtended by same arc)
iii) DOC = 72⁰
(angle in a ? )
iv) OCA= 63⁰
(base angles of isosceles ?)
v)DEB-630
(angles subtended by same arc)
