Question

The lines ab and CD intersect at a point o. If angle aoc=40 degree find the measure of each of the angle aod,angle bod and angle boc

Answer 1

Answer:

as angle aoc=40 degree angle DOB  will also be of 40 degree by verticaly opposite angles

Step-by-step explanation:

so angle AOD + angle DOB =180 (LINEAR PAIR)

SO ANGLE AOD WILL BE 180-40=140 DEGREE

SIMILARLY ANGLE BOC WILL BE 140 DEGREE BY VERTICALLY OPPOSITE ANGLES WITH ANGLE AOD

HENCE ANGLE AOD=140 degree

ANGLE DOB=40 degree

AND ANGLE BOC=140 degree

hope this helps u mark it as brainliest and please thank me

Answer 2

Answer:

the angle aod will be 140°(linear pair ) and angle dob will be 40°(alternate apposite angle )angle boc will be 140°(linear pair)
