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)}

The sum of three consecutive even numbers is 36. what is the smallest of these numbers?
kap26 [50]

。☆✼★ ━━━━━━━━━━━━━━  ☾

Call the first even number '2n'

Thus, the next would be 2n + 2

And the next would be 2n + 4

Form an equation:

2n + 2n + 2 + 2n + 4 = 36

Simplify:

6n + 6 = 36

Subtract 6 from both sides:

6n = 30

Divide both sides by 6:

n = 5

2(5) = 10

The smallest number is 10

Have A Nice Day ❤
