Answer:
![x = 9](https://tex.z-dn.net/?f=x%20%3D%209)
![y = 17](https://tex.z-dn.net/?f=y%20%3D%2017)
Step-by-step explanation:
This is a cyclic quadralterial so opposite angles are supplementary.
The x variables add up to 180 so
![11x + 8 + 8x + 1 = 180](https://tex.z-dn.net/?f=11x%20%2B%208%20%2B%208x%20%2B%201%20%3D%20180)
![19x + 9 = 180](https://tex.z-dn.net/?f=19x%20%2B%209%20%3D%20180)
![19x = 171](https://tex.z-dn.net/?f=19x%20%3D%20171)
![x = 9](https://tex.z-dn.net/?f=x%20%3D%209)
The y variables add up to 180.
![6y - 4 + 5y - 3 = 180](https://tex.z-dn.net/?f=6y%20-%204%20%2B%205y%20-%203%20%3D%20180)
![11y - 7 = 180](https://tex.z-dn.net/?f=11y%20-%207%20%3D%20180)
![11y = 187](https://tex.z-dn.net/?f=11y%20%3D%20187)
![y = 17](https://tex.z-dn.net/?f=y%20%3D%2017)

Answer:
D. 1/2
Step-by-step explanation:
Coin tosses are independent. Past results don't affect future probabilities. So the probability of getting heads on the fourth toss is still 1/2.
