Question

8. Lines AB and CD intersect at point O. Write in degree the measure of the angle between bisectors of <AOC and <BOC.
please help me ​

Answer 1

Answer:

90⁰

Step-by-step explanation:

let the Lines AB and CD make an angle of <AOC =40⁰ and <AOD = 140⁰

AOD and BOC are opposite angles therefore the angle measure is same =140°

therefore bisector of angle BOC will make angle

140/2=70⁰----------------(1)

bisector of angle AOC will make angle

40/2=20⁰------------------(2)

therefore considering common side OC ,

angle between the bisectors =70⁰+20⁰=90⁰--------(from (1) and (2))
