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:
He had 38
You simply multiply the number by 2 because it's half.
Answer:
You will need to convert to degrees when you are taking a right-triangle approach to trigonometry. In other words, if you are not utilizing aspects of the unit circle, you should convert to degrees. The opposite would go for radians. When you are taking a unit circle approach, convert degrees to radians.
