Answer:
Angle A = 84 Angle B=50 Angle C = 96 Angle D =130
Step-by-step explanation:
We know that in a cyclic quadrilateral,
Opposite angles are supplementary
Therefore equations become
2x+4+4y-4= 180
x+10+5y-5 = 180
Solving these u would get the answer

2x+4 + 4y-4= 180 ( as the sun of the opposite angles in a cyclic quadrilateral is 180)
2x+4y=180 —(1)
Similarly
X+10+5y+5=180
x+5y=165 —(2)
Multiplying equation (2) with 2
2x+10y=330
Elimination method
2x+10y=330
-2x-4y=-180
6y=150
y=150/6
Y=25
Putting y in eq.(1)
2x+100=180
x=40
2x+4y=180 —(1)
Similarly
X+10+5y+5=180
x+5y=165 —(2)
