Answer:
the angle between their paths is <em>100.8°</em>
Step-by-step explanation:
From the given information, you can construct a triangle, just like the one in the figure.
We will use the <em>Cosine Rule</em> which is:
c² = b² + a² - 2 b c cos(θ)
where
- c = 16 miles
- b = 8 miles
- a = 12 miles
Therefore,
2 b c cos(θ) = b² + a² - c²
cos(θ) = (b² + a² - c²) / 2 b c
θ = cos⁻¹( (b² + a² - c²) / (2 b c) )
θ = cos⁻¹( (8² + 12² - 16²) / 2(8)(16) )
<em>θ = 100.8°</em>
<em></em>
Therefore, the angle between their paths is <em>100.8°</em>
Answer:
Both plant and animal cells can have endoplasmic reticulum. Both plant and animal cells can have mitochondria. In animal cells, chromosomes contain the master plan for cell activities and cell development. The cell membrane controls which substances enter and leave a plant cell
Step-by-step explanation:
3x+22=10x-41
-22 -22
----------------------
3x=10x-63
-10x -10x
-----------------
-7x=-63
divide by -7 on both sides
yep ur right its x=9
Add 25 to both sides x-25 +25 =7 +25
x =32
Answer:
2/145
Step-by-step explanation:
