Answer:
=> x° + 57° + (43°+24°) = 180° ------------ (angle sum property of ∆)
=> x° + 57° + 67° = 180°
=> x° + 124° = 180°
=> x° = 180° — 124°
=> x° = 56°

=> x° + y° + 43° = 180° ------------- (angle sum property of ∆)
=> 56° + y° + 43° = 180°
=> y° + 99° = 180°
=> y° = 180° — 99°
=> y° = 81°

______________________________
=> y° + z° = 180° ------------- (Linear pair)
=> 81° + z° = 180°
=> z° = 180° — 81°
=> z° = 99°
Step-by-step explanation:
so,
x° = 56°
y° = 81°
z° = 99°
