Answer:

<u><em>Approximately 600 miles</em></u>

Explanation:

There are several ways to solve this using different assumptions.

First you need to imagine an isosceles triangle formed by:

the equal sides of the triangle are the distance between the Earth and the Moon: 234,000 miles

the included angle is 30 second of degree

the base side of the triangle, opposed to the 30 seconds angle, is how far in miles from its assigned target the laser beam is: x

You can solve for x in several ways.

I will use the cosine rule:

$c^2=a^2+b^2-2accos(\alpha)$

Where:

$c=x\\\\a=234,000miles\\\\b=234,000miles\\\\\alpha=30seconds$

One second of degree equals 1/3600 degrees:

$30seconds\times 1degree/3600seconds=1/120degrees$

Substitute in the equation and compute:

$x^2=(234,000miles)^2+(234,000miles)^2-2(234,000miles)(234,000miles)\times cos(1/120\º)$

$x=579.15mile\approx600miles$

Answer:

x = -5/2

Step-by-step explanation:

4x+2 = -8

We are solving for x

The first step in isolating x is to subtract 2 from each side

4x+2-2 = -8-2

4x = -10

Divide each side by 4

4x/4 = -10/4

x = -10/4

Simplify the fraction

x = -5/2
