A guy wire to a tower makes a 72 degrees angle with level ground. At a point 30 ft farther from the tower than the wire but on t
Andreyy89
So.. checking the picture below

we can say y = y, or just do a substitution and end up with

\bf tan(72^o)=tan(30^o)(30+x)\implies 3.08x=\cfrac{30}{\sqrt{3}}+\cfrac{1}{\sqrt{3}}x
\\\\\\
3.08x-\cfrac{1}{\sqrt{3}}x=\cfrac{30}{\sqrt{3}}\implies 2.5x\approx 17.32\implies x\approx \cfrac{17.32}{2.5}

once you know, how long is "x", then you can simply use the cosine of 72° to get "r"

thus    \bf cos(\theta)=\cfrac{adjacent}{hypotenuse}\qquad cos(72^o)=\cfrac{x}{r}\implies r=\cfrac{x}{cos(72^o)}

Answer:  At noon the temperature outside of Hector's home was 4 degree warmer than the temperature outside of gale's home.  

Step-by-step explanation:

Here, x represents the number of hours after noon while g(x) and f(x) represents the temperature of gale's and hector's home respectively in x hours.

Since, at noon, x = 0

And, by the table g(x=0) = -1

That is, the temperature of gale's home is -1° F at noon.

And, by the given graph, f(x=0) = 3

That is, the the temperature of hector's home is 3° F at noon.

And,  f(0)-g(0) = 3-(-1) = 4°F

That is, the difference between  the temperature of hector's home at noon and the temperature of gale's home at noon is 4°F.
