Question

9. In the given figure, two straight lines AB and CD intersect at a
point o
If AOC = 42°, ſind the measure of each of the angles:
(i) AOD (ii) BOD (iii) COB ​

Answer 1

the option is BOD it is helpful to u

Answer 2

Answer:

Angle AOC = 42

Angle AOC =Angle BOD [vertically opposite angles ]

therefore Angle BOD= 42

Angle BOD+Angle AOD =180

42+x=180

x=180-42

x=138

Then, Angle AOD=Angle BOC [vertically opposite angles ]

therefore, Angle BOC=138
