A hot air balloon is flying above Grovenburg. To the left side of the balloon, the balloonist measure the angle of depression to

the Groveburg soccer fields to be 20 degrees 15’. To the right side of the balloon, the balloonist measures the angle of depression to the high school football field to be 62 degrees 30’. The distance between the two athletic complexes is 4 miles.

Find enclosed file with a drawing and the calculations of all angles and all distances.

These are the results that you will find in it:

<span>Angle x = 90° - 22°15’  </span>

Angle y = 90° - 62°30'

Angle z = 22°15’ = 22.25°

Angle w = 62°30’ = 62.50°

 

tan(z) = H/a => a = H/tan(z)

tan(w) = H/b => b = H/tan(w)

 

a+b = 4 => H/tan(z) + H/tan(w) = 4 => H [1/tan(z) + 1/tan(x) ] = 4

 <span>   </span>H = 4 / {[1/tan(z) + 1/tan(x) ] } = 1.35 miles

<span>    </span>a = 1.35 / tan(22.25°) =  3.30 miles

<span>    </span>b = 4 – 3.30 = 0.7 miles

I hope it is very useful and you understand it. Let me know.

Which phrase best describes sir isaac newton's contributions to modern science and therefore to the industrial revolution?
astraxan [27]
Can you please give the phrases? 

But, I'll help what I can.

First, he was the first to discover gravity. He was not bonked by the head by an apple, rather he watched an apple fall from a tree before he decided to explore gravity further. 

He was also the first scientist to be knighted, which is a great honor, as you can expect. 

Newton also developed The Three Laws of Motion. They are extremely important to physics and are considered some of the foundation for physics today. 

He also discovered calculus, which is complex math that is very helpful to scientists today. 

He also discovered the color spectrum using a glass prism, a dark room and window shade with a hole in it. He was able to project the color spectrum onto a piece of paper.

Those are the few I can think of now, but hope it helps!
