Question

If 0 be the centre of the circle , Find the value of x in the circle ​

Answer 1

Answer:

Here,The value of x in the circle is 55°.

Step-by-step explanation:

Here, As per our given question,

O is the centre of the given circle,

And angleAOB =70°

=So, OA=OB (Radius of the same circle drawn from the centre)

So, angleOAB=angleOBA (Opposite angles of equal opposite sides are also equal)

So, angleOAB+angleOBA=2x

So, now, 2x+70°=180° (Sum of all angles =180° in a triangle)

=2x+70°=180°

=2x=180°-70°

=2x=110°

=x=110°/2

=x=55°

So, Here the value of x in the given circle is 55°.
