Question

pls give answer with full solution ​

Answer 1

2. C =40

D=50

O=90

Alternate Angles are equal

Answer 2

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
