102 +y =180( the sum of opp. angle of a cyclic quad.)
y = 78
2y = x (angle subtended by an arc at the centre is double by any point on the circle)
x =156
x +z+102+26=360( angle sum property of a quadrilateral )
z=360-26-102-156=76
y = 78
2y = x (angle subtended by an arc at the centre is double by any point on the circle)
x =156
x +z+102+26=360( angle sum property of a quadrilateral )
z=360-26-102-156=76

when u have given so what my reasons will change.
no problem
u have luck with u
its not luck
so what is it
okay now leave ot

102°+y°=180°
y°= 180°-102°
y°=78°
x=2y
x=2×78°
x=156°
x+z+102°+26° =360°
156°+z+128°=360°
z=360°-284°
z=76° Ans.
