Question

10. In the given figure, two straight lines AB and CD intersect at a point
0. If ZBOD = 40°, find the measure of each of the angles, ZBOC,
ZAOC and ZAOD.
40°
D
180​

Answer 1

AngleCOA=40
AngleCOB=140
AngleAOD=140

Hope it helps you

Answer 2

Answer:

Since Angle BOD and Angle AOC are vertically opposite angles, Angle AOC becomes 40 degrees. BOC = 180-40 =140 degrees. AOD =140 degrees.
