Find angle ABD
Step by step explanation please.​

Answer 1

Answer:

Hello mate.

Step-by-step explanation:

HEY MATE.....

Angle AOB = 30°

So, Angle COD = 30° (Vertically Opposite Angles)

Now, Angle OCD = Angle ODC (Since OC = OD)

Let Angle OCD = Angle OCD = x

Do, Angles

COD + OCD + ODC = 180° (Angle-sum property)

=) 30°+ x + x = 180°

=) 30°+ 2x = 180°

=) 2x = 180° - 30°

=) 2x = 150°

Therefore, x = Angle OCD = 150°÷2 = 75°

HOPE IT HELPS.....
