That was the saddest day of my life. When I was 16 my best friend, who I grew up with, was diagnosed with cancer and died not long after that. It didn't hit me what had occurred until I'm staring at her casket before it was lowered.

11 years later I'm still pissed off about how unfair it all feels. She was the kind of girl that never did anything wrong in life, ever. She wasn't far from getting her pilots license. Had straight A's that never went lower than a 98 and she was a fantas artist. All of that potential. Gone.

"Finally, I understand why she did it." You want me to tell you before I hear this, it's a sad story. On a very depressing day with nothing but sleep I was on my way home suddenly, I saw a woman playing with a doll near the football field, I felt very strange because she was too big to play a doll muscular, but I asked someone nearby and he told me that the previous single woman and Love A man soon married, they lived for a while and left each other. After that, they divorced but at the same time they were also women with children for 3 months. year old. After that, she still tried to raise her child without giving it up. After growing up, the baby is a very beautiful girl. On the 8th birthday, the mother is too busy to work. The girl who had a traffic accident when she came home alone at that time, the woman holding that gift suddenly heard that her daughter had an accident that she was so desperate that I quit eating and working. But I don't know why she changed her freedom for now because of a happy 3-year-old child and every afternoon she goes to the soccer field where her son and she used to play and sit and talk to I realized that she was a strong woman because of her

Don't worry about me, I'm still with you, but if you cry, I'll be sad so please smile, I think there might be a message that says that someone invited me to drink and I didn't do anything. Turn it off and come back with a family meal.

Does your father playing with children ?

is your father ...

a. Ta có: \(\hat{AOA_1}=2^o,\hat{AOA_2}=4^o,...\Rightarrow\hat{AOA_{50}}=100^o\)

Mà \(\hat{AOB}\) là góc bẹt \(\Rightarrow\hat{AOB}=180^o\)

\(\Rightarrow\hat{A_{50}OB}=\hat{AOB}-\hat{AOA_{50}}=180^o-100^o=80^o\)

- Mặt khác: \(\hat{BOB_1}=1^o,\hat{BOB_2}=3^o,...\Rightarrow\hat{BOB_{50}}=99^o\)

Tương tự như trên: \(\Rightarrow\hat{AOB_{50}}=\hat{AOB}-\hat{BOB_{50}}=180^o-99^o=81^o\)

- Từ đó suy ra: \(\hat{A_{50}OB_{50}}=\hat{AOB}-\hat{AOB_{50}}-\hat{A_{50}OB}=180^o-81^o-80^o=19^o\)

b. Dựa vào a. ta suy ra được công thức sau:

\(\hat{A_nOB_m}=\hat{AOB}-\left(\hat{AOB}-\hat{AOA_n}\right)-\left(\hat{AOB}-\hat{BOB_m}\right)\)

\(=\hat{AOB}-\hat{A_nOB}-\hat{AOB_m}\)
