Jaldi karo plzzz

Answer 1

. 180°-120°=60° 60°+90°=150° than 180°-150°=30° than angle C and angle D is equal

Answer 2

Héyãâà mate:-

Let us consider a another point say E

Than EOC will be a right angled triangle where E is the right angle


Now,

We know that,

Sum of adjacent Angle is 180°

So ,

120 - x = 180°

x = 60°

Now we know that angle E is 90°

The sum of a triangle is 180°

So,

60° + 90° + C = 180°

=> C = 180° - 150° = 30°

If C = 30°

Than Angle D = 30° ( opposite angle are equal).

Hope it helps you

Thanks
