Question

In the given figure, AOB =​

Answer 1

Step-by-step explanation:

angle ODC = 90°

angle AOD = 140°

angle BOC= 40°

so angle AOB = 360° - sum of all other angles

= 360° -270°

= 90°

Answer 2

Answer:

in the given figure

AOD+DOC+BOC+AIB= 360°

140+90+40+x=360°

270+x = 360°

x = 360-270

x = 90°
