Answer:
[tex]w=y=54^\circ,\ x=z=20^\circ[/tex]
Step-by-step explanation:
[tex]\text{1. }w=y=\dfrac{1}{2}\times108^\circ\ \ \ [\text{Inscribed angle is half of its intercepted arc.}]\\\\\text{or, }w=y=54^\circ\\[/tex]
[tex]\text{2. }x=z=\dfrac{1}{2}\times40^\circ\ \ \ [\text{Inscribed angle is half of its intercepted arc.}]\\\\\text{or, }x=z=20^\circ[/tex]
