Let's do this question, A and B are tangents to the given circle.
Angle ACB is equal to 60 degrees, find angle it be all right, pause the video, give it a try and
then let's do it together.
All right, we're back.
Let's do it together and we'll be a B is equal to 60 degrees also right angle Déby this one also will
be 60 degrees because this angle is 60 degrees as per second tangent theorem.
Right.
Why is that so?
Over here you have AB ABS is making an angle with a tangent 80 over here.
So this angle will be equal to the angle substandard by AB, which is 60 over here.
Right.
This is also 60 in a similar manner.
You can see that angle, a beauty.
That's this angle over here that will also be equal to 60 degrees.
Right, because of the same reason you have another tangent and that's forming with the second angle
equal to the angle neck by this second over here.
But this angle also is equal to 60 degrees.
Therefore, we find that angle.
EDB is equal to 180 minus 60, minus 60.
That's 180 minus 120, which is equal to 60 degrees.
And that is your answer.
