Question

Two lines AB and CD intersect at O.If angle Aoc=50°,Find angle AOD angle, BOD and angle BOC.​

Answer 1

Answer:

angle AOC=50°

so angle DOB=50°[by Vertically opposite angle]

Now angle (AOC+COB)=180(by Linear pair)

so 50°+COB=180°

or COB=180°-50°

or COB=130°

Now angle COB =angle AOD(by Vertically opposite angle)

so angle AOD =130°

Hence angle AOD= 130°

COB=130°

&DOB=50°
