Mathematics

  945° | 360°
 -720     2
  225°

So we say that this value corresponds to 2 laps plus the rest 225°.

However, since it has a negative sign, it says that it is oriented 360 ° at 0 °.
360° - 225°

135°

Soon:

cos -945° = cos 135°

cos -945° = (-√2÷2) or -0,70

defon

9514 1404 393

Answer:

  • width: 9 m
  • length: 13 m

Step-by-step explanation:

Let w represent the width. Then the length is 2w-5, and the perimeter is ...

  P = 2(L+W)

  44 = 2((2w-5) +w)

  44 = 6w -10

  54 = 6w

  9 = w

  2(9) -5 = 13 = length

The length of the rectangle is 13 meters; the width is 9 meters.
