Question

if four angles of a cyclic quadrilateral are (2x - 1) , ( y + 5), ( 2y + 15 ) and ( 4x - 7) , then
1. x=50, y= 33
2.x=30 , y=53
3.x=40 , y=43
4. x =33, y=50​

Answer 1

Answer:

Step-by-step explanation:

1)x=50,y=33

2x-1=99

y+5=38

2y+15=81

4x-7=193

2)x=30,y=53

2x-1=59

y+5=58

2y+15=121

4x-7=113

3)x=40,y=43

2x-1=79

y+5=48

2y+15=101

4x-7=153

4)x=33,y=50

2x-1=65

y+5=55

2y+15=115

4x-7=125
