Next week , In my free time, I love to relax myself by listening to music and watching my favorite films. I study all day, so after 7PM is the only time that I can use for myself. I have a smart phone, so I can download a lot of songs from the Internet for free, and I usually hear them with my headphone. Sometimes when my parents are not at home, I turn on the loudspeakers to have the best experience with music, but most of the time I just listen in silence. Besides music, movies are my biggest love. When I am not listening to the songs, I turn on my computer and watch some of the lasted movies on the websites. Since most of the best films are from Europe and America, this is also a way for me to improve my English skills. I usually do not use the subtitle, and I try to hear directly what the actors and actresses are saying. My parents want me to read books to even learn in my free time, but I think I should do what I actually love to make myself comfortable.

a, Xét \(\Delta\)ABC có: AB² + AC² = 6² + 4,5² = 56,25  (cm²)

                        BC² = 7,5² = 56,25  (cm²)

AB² + AC² = BC² vậy tam giác ABC vuông tại A (đpcm) 

SinC = 6 : 7,5  =0,8 ⇒ \(\widehat{C}\) = 53,13⁰ ⇒ \(\widehat{B}\) = 90⁰ - 53,13⁰ = 36,87⁰

b, Dựng hình chữ nhật ABCD, chiều cao AH, DK, và đường thẳng d đi qua D song song với BC  như hình vẽ ta có

S_ABC = S_BDC ⇒ AH = DK 

Lây 1 điểm bất M kỳ di động trên đường thẳng d ta có:

S_BDC = S_MBC  (vì hai tam giác có chiều cao bằng nhau và chung cạnh đáy BC)

⇒ S_ABC = S_MBC

Kết luận khi M di động trên đường thẳng d thì diện tích tam giác MBC luôn bằng diện tích tam giác ABC
