Angle XYZ is inscribed in a circle with centre O. If Angle XYZ = 35 degree , find the measureof the arc intercepted by Angle XYZ . |

Answer» Step-by-step explanation: OY=OZ=radius=r Given YZ=r ⟹△OYZ is equilateral ⟹∠YOZ=60 ∘
We know that angle MADE by a CHORD on any point on the circle is HALF the angle made by the chord at the center ⟹∠YXZ= 2 ∠YOZ
⟹∠YXZ= 2 60
=30 ∘ |
