CAN SOMEONE PLS HELP?? IM AB TO FAIL GEOMETRY AND NEED HELP W LAW OF SINES. PLEASE
valkas [14]
The laws of sines is already indicated in the provided images.

1. sin20/3.3 = sinC/5.4
Thus, angle C is 34.03 degrees. To find angle B: 180 - 20 - 34.03 = 126 degrees. Using the law of sines,

sin20/3.3 = sin(126)/b
b = 7.8 units

From this answer, we can already tell that the answer is letter C: <span>3 units and 7.8 units.

2.  Angle J = 180 - 120 - 40 = 20 degrees. Then,

sin(20)/2 = sin(120)/k
k = 5.1 units</span>

Answer:

  • 320 m after 8 seconds
  • 5.6 seconds, 10.4 seconds to height of 290 m

Step-by-step explanation:

To find the height at 8 seconds, evaluate the formula for t=8.

  S(t) = -5t^2 +80t

  S(8) = -5(8^2) +80(8) = -320 +640 = 320

The height of the rocket is 320 meters 8 seconds after takeoff.

__

To find the time to 290 meters height, solve ...

  S(t) = 290

  290 = -5t^2 +80t

  -58 = t^2 -16t . . . . . . . divide by -5

  6 = t^2 -16t +64 . . . . . complete the square by adding 64

  ±√6 = t -8 . . . . . . . . . take the square root

  t = 8 ±√6 ≈ {5.551, 10.449}

The rocket is at 290 meters height after 5.6 seconds and again after 10.4 seconds.
