Gustavo and Aiden are walking due west through the forest when they happen upon an angry grizzly bear. Gustavo runs away 23^\cir
Harlamova29_29 [7]

Answer:

They are 261.96 meters apart.

Step-by-step explanation:

From the question, considering a North, East, South and west pole, Gustavo ran 23° above the east horizontal, while Aiden ran 33° below the east horizontal.

Thus, the total angle between them is 23 + 33 = 56°.

Therefore, let the distance between them be c and we can calculate that using the cosine law. Thus,

c² = a² + b² – 2ab cos θ

Where a and b are distances travelled respectively by Gustavo and Aiden. While θ is the angle between them.

Thus,

c² = 300² + 250²– 2(300) (250)cos 56

c² = 90000 + 62500 - 83878.9355

c² = 68621.0645

c = √68621.0645

c = 261.96 m

They are 261.96 meters apart.

Input in stand form the equation of the given line.
Daniel [21]

Answer:

  3x +8y = -17

Step-by-step explanation:

The point-slope equation is a good place to start.

  y -k = m(x -h) . . . . . equation through (h, k) with slope m

Filling in your numbers gives ...

  y +4 = -3/8(x -5)

Multiplying by 8, we get

  8y + 32 = -3x + 15

Adding 3x-32 puts this in standard form.

  3x + 8y = -17

_____

Standard form is ...

  ax +by = c

where a, b, c are mutually-prime integers and the leading coefficient is positive. (If a=0, the leading coefficient is b.)
