(a).ABO is equivalent to x because they are base angles of an isosceles triangle (because the radii are equal). The same applies for CBO being equivalent to y
(b). Since angle COA is 180°, ABC is equivalent to half of COA which is 90°

Answer:

Option B is the right choice.

Step-by-step explanation:

Given:

An are CE and an inscribed angle CBE.

Measure of inscribed angle CBE = 25 °

We have to find the measure of the arc CE.

Concept:

An inscribed angle is an angle with its vertex on the circle.
The measure of an inscribed angle is half the measure the intercepted arc.
Measure of inscribed angle = 1/2 × measure of intercepted arc .

To find the measure of arc CE.

⇒ $\angle CBE = \frac{1}{2} \times m\ (arc\ CE)$

⇒ $2\times \angle CBE = m\ (arc\ CE)$

⇒ $2\times 25 = m\ (arc\ CE)$

⇒ $50 = m\ (arc\ CE)$

Measure of intercepted arc CE = 50 degrees.

The measure of arc CE = 50° so, option B is the right choice.
