2. C =40
D=50
O=90
Alternate Angles are equal
Verified answer
Answer:
<C=40°,<D=50°,<AOB= 90°, <COD=90°
Step-by-step explanation:
Since, AB is parallel to CD
This implies that <A=<D=50°
and <B=<C=40°
In triangle AOB, we know that the sum of all angles is 180°
so <AOB=180-(40+50)
=<AOB =90°
and <AOB and <COD are vertically opposite angles
so <AOB =<COD
