Question

please give me answers of this question ​

Answer 1

Answer:9 (a) 11/30 (b) 19/30

6 x=95 y=80

Step-by-step explanation:

ABCD is a cyclic quadrilateral.

AngleA +angleC = 180

100+c=180

C=80.

AngleD +angleB =180

85 +b=180

B=95.

Answer 2

Answer:q no 6

We know that sum of opposite angles of a cyclic quadrilateral measures 180

So angle a + angle c = 180

100+y = 180

Y =180-100=80

Similarly angle x = 180-85= 95
