Step 1.

Calculate measure of angle α:

$47^o-38^o=9^o$

Step 2.

Calculate what fraction of the angle 360° is the angle α:

$\dfrac{9^o}{360^o}=\dfrac{1}{40}$

Step 3.

Calculate the circumference of the Earth (circle):

$C=2\pi r\to C=2\pi\cdot4000=8000\pi\ mi$

Step 4.

The length of arc is equal 1/40 of the circumference:

$\dfrac{1}{40}C=\dfrac{1}{40}\cdot8000\pi=200\pi\ mi$

$\pi\approx3.14\to\dfrac{1}{40}C\approx200\cdot3.14=628\ mi$

<h3>Answer: A) 628 miles</h3>

Answer:

Option B is the correct answer

Step-by-step explanation:

Hope it helps you in your learning process.

$\tan 30\degree=\frac{17}{x}$

$\implies\frac{1}{\sqrt 3}=\frac{17}{x}$

$\implies\huge{\red{ x={17\sqrt 3}}}$

$\sin 30\degree=\frac{17}{y}$

$\implies\frac{1}{2}=\frac{17}{y}$

$\implies\huge{\purple{ y={34}}}$
