Sagot :
Answer:
- Inscribed angle is half of the intercepted arc.
- Central angle is the same size as the intercepted arc.
As per above two statements we have:
- y = 2*58° = 116°
and
- z = 90°/2 = 45°
Answer:
y=58×2=116 central angle of the cyclic quadrilateral is double if inscribed angle
z=90/2=45
inscribed angle is half of central angle of the cyclic quadrilateral
