★Answer→
angle COD = 100°
★Solution→
angle BAC = 20°
angle BAC = angle OCA = 20°
[ OA = OC]
again,
angle BAC = angle ACD = 20°
[AB||CD]
So,
angle OCD = angle OCA + angle ACD
→ angle OCD = 20°+20°
→ angle OCD = 40°
angle OCD = angle ODC = 40°
[ OD = OC]
∆ COD is a triangle.
• We know that the sum of the three angles of the triangle is 180°.
angle COD = 180° - ( 40°+40°)
= 180°-80°
= 100°
So, angle COD = 100°
•Hope it will help you.
