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
SABC = SBDC ⇒ AH = DK
Lây 1 điểm bất M kỳ di động trên đường thẳng d ta có:
SBDC = SMBC (vì hai tam giác có chiều cao bằng nhau và chung cạnh đáy BC)
⇒ SABC = SMBC
Kết luận khi M di động trên đường thẳng d thì diện tích tam giác MBC luôn bằng diện tích tam giác ABC
1.This is Peter 's book.
2. Let go to the Smiths'.
3. The children 's room is upstairs.
4. John 's sister is twelve years old.
5. Susan and Steve 's school is old.
\(5.\left(x-1\right)-206=2^4.4\\ \Rightarrow5.\left(x-1\right)-206=16.4\\ \Rightarrow5.\left(x-1\right)-206=64\\ \Rightarrow5.\left(x-1\right)=270\\ \Rightarrow x-1=54\\ \Rightarrow x=55.\)
5.(\(x-1\)) - 206 = 24.4
5.(\(x-1\)) - 206 = 64
5.(\(x-1\)) = 64 + 206
5.(\(x-1\)) = 270
\(x-1\) = 270 : 5
\(x-1\) = 54
\(x=55\)
