In ∆OAB
∵ OA = OB (radii of a circle)
∴ ∠OBA = ∠OAB (Opposite angle of the equal side of triangle)
∴ ∠OAB = 32°
⇒ ∠x = 32°
(∠OBA = 32°) …..(i)
Again, PAQ the tangent at point A of circle and OA is radius.
∴ OA ⊥ PQ
⇒ ∠OAQ = 90°
∴ ∠BAQ + ∠OAB = 90°
∴ ∠BAQ + 32° = 90° [∵ ∠OAB = 32°]
∠BAQ = 90° – 32° = 58°
∠BAQ = ∠ACB [angle made in alternate segment]
58° = ∠y
∠x = 32°, ∠y = 58°
