Question

find the angle COD?​

Answer 1

Step-by-step explanation:

angle COD is 90 degree becouse angle drown in semi circle is always 90

Answer 2

★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.
