Answer:
x = 99°
y = 91°
Step-by-step explanation:
For Cyclic quadrilateral, the sum of the opposite angles = 180°
Let's find x :-
x + 81° = 180°
x = 180 - 81
x = 99°
Let's find y :-
y + 89° = 180°
y = 180 - 89
y = 91°

<span>Sin(-x) = -sin x for all values of x, IT IS TRUE
Because sinx is an odd function</span>
Distribute the negative sign
![7x^2-3x-6](https://tex.z-dn.net/?f=7x%5E2-3x-6)
Combine like terms
-9x^2 + 7x^2 = -2x^2
9x - 3x = 6x
13 - 6 = 7
![-2x^2 +6x + 7](https://tex.z-dn.net/?f=-2x%5E2%20%2B6x%20%2B%207)
