Question

calculate
1.angleODA
2.angleOBC​

Answer 1

Answer:

angle ODA is 54⁰

and angle OBA is 40⁰

Step-by-step explanation:

angle ODAand OAB measures are same

• but angle OBC equal to 40⁰ because angle o is 70⁰ (vertically opposite angle to angle DOC) and angle OAB is already determine 54⁰ so due to ANGLE SUM PROPERTY OF TRIANGLE WILL BE 180⁰ SO 180⁰- (angle AOB + angle BOA) : THEN IT WILL BE 180⁰-120⁰ =40⁰ ANSWER
