Pls help me solve pls show how you got the answer

Given:

The figure of a circle O.

To find:

The value of x.

Solution:

First, label some points on the given figure as shown below.

In triangle BOC,

                (Radii of same circle)

It means is an isosceles triangle and the base angles of an isosceles triangles are congruent. So,

In triangle ,

         (Angle sum property)

Now,

Using the central angle theorem, we get

Therefore, the correct option is B.

step-by-step explanation:

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.
