WebExample 2: Consider the circle given below with center O. Find the angle x using the circle theorems. Solution: Using the circle theorem 'The angle subtended by the diameter at the circumference is a right angle.', we have ∠ABC = 90°. So, using the triangle sum theorem, ∠BAC + ∠ACB + ∠ABC = 180° ⇒ x + 55° + 90° = 180° ⇒ x + 145° = 180°
