Answer:
The answer to your question is:
a) 8.2 mi
b) 4.1 mi
c) 4.7 mi
Step-by-step explanation:
For 30°
sin Ф = opposite leg / hypotenuse
hypotenuse = opposite leg / sin 30
hypotenuse = 4.1 / sin 30 = 4.1 / 0.5
hypotenuse = 8.2 mi
For 90°
d must be 4.1 mi because is over the observer at this angle
For 120°
distance = opposite leg / sin 60
distance = 4.1 / √3/2
= 4.71 mi
I hope it helps you!
X² + 2x = 24
Organizing:
x² + 2x - 24 = 0
<<<< (<em>Quadratic </em><span><span><em>equation</em>)
</span>
</span><span>Delta:
</span>Δ = b²<span> - 4.a.c </span>
Δ = 2²<span> - 4 * 1 * -24 </span>
<span>Δ = 4 - 4 * 1 * -24 </span>
Δ = 100
<span>Bhaskara:
</span><span>x = (-b +- √Δ)/2*a
</span>
x' = (-2 + √100)/2*1
x' = 8 / 2
x' = 4
x'' = (-2 - √100)/2*1
x'' = -12 / 2
x'' = -6
Result: x = 4 or<span> x = - 6 .

Good studies! :)
D because of the distributive property
things were not as complicated when I was in middle school.
