ABCD IS cyclic quad.
A + C =180
7y-21=4y+3
7y-4y=3+21
3y=24
y=8
therefore
A=7(8)-21=35
A + C =180
7y-21=4y+3
7y-4y=3+21
3y=24
y=8
therefore
A=7(8)-21=35

A+C=180°.........(by cyclic quadrilateral
theorem)
7y-21+4y+3=180°
11y-18=180°
11y=180+18
11y=198
y=198/11
y=18
therefore
A=7y-23
A=7×18-23
A=136-23
A=113°
