Here are the solutions to the problem: a) Giving reasons or otherwise, Find the value of the following angles a) (i) Angle CBA Step 1: The problem states that A, O, X, and C are points on a straight line. Since O is the center of the circle and A and C are on the circumference, the line segment AC must be a diameter. Step 2: The angle subtended by a diameter at any point on the circumference is 90°. Step 3: ∠ CBA is subtended by the diameter AC at point B on the circumference. ∠ CBA = 90° Reason: Angle in a semicircle. The value of Angle CBA is $9

A) Giving reasons or otherwise, Find the value of the following angles: a) (i) Angle CBA

Step-by-step solution

The problem states that A, O, X, and C are points on a straight line.

The angle subtended by a diameter at any point on the circumference is $90^\circ$ .

$\angle CBA$ is subtended by the diameter AC at point B on the circumference.
