GarryVolchara [31]
We know that

<span>comparing the problem with the geometry, the rectangle with the largest area (maximum product of two numbers) is the square.

: Cho tam giác ABC vuông tại C, trong đó AC = 0,9m, BC = 1,2m. Tính các tỉ số lượng giác của góc B, từ đó suy ra các tỉ số lượng
Xelga [282]

Answer:

Step-by-step explanation:

Vì tam giác ABC vuông tại C nên ta áp dụng định lí pitago=> AB²=AC²+BC²=0.9²+1.5²=3.06=>AB= (3 căn bậc hai của 34)/10

sin B=AC/AB=(3 căn bậc hai của 34)/34

cos B=BC/AB

tan B= AC/BC

cot B= BC/AC

Tương tự suy ra tỉ số lượng giác góc A

Step-by-step explanation:

<u>There is one possible way:</u>

  • (4x² - 47x + 141)/(x² + 13x + 40) =
  • (4x² + 4*13x + 4*40 - 47x - 52x - 160 + 141)/(x² + 13x + 40) =
  • 4  - (99x + 19)/(x² + 13x + 40)
