Do alto de um farol cuja altura é de 20 m avista se um navio sob ângulo de depressão de 30°. A que distância , aproximadamente,
Mkey [24]
Esta é a trigonometria . Se você desenhar uma linha a partir do topo da casa de luz para o barco, você terá a hypotonuse de um triângulo. Um truque é lembrar que este é um triângulo especial. É um triângulo 30-60-90 , que tem propriedades especiais mostradas na fixação abaixo . por isso sabemos que o lado adjacente que não é o hyposonuse é x√3 . Agora sabemos que x<span>√3 = 20
Solve for x.
x</span><span>√3=20
divide both sides by </span><span>√3.
x=20/(</span><span><span>√3)
</span>Try not to have square roots (</span><span><span>√)</span> in denomenator so multiply top and bottom by </span><span>√3 and get
x=(20</span><span>√3)/3
x is what we are looking for so the answer is </span>
20<span>√3 m </span><span>ou cerca de 34.64 m</span>

A line contains the points (-7,15) and (10,27) what is the slope of the line as a simplified fraction?
Gwar [14]

Answer:

The slope of line for given points is   \frac{12}{17}

Step-by-step explanation:

Given points of line as :

A  = ( - 7 , 15 ) i, e x_1 = - 7 ,  x_1 = 15

B = ( 10 , 27 )  i.e  x_2 =  10 , y_2 = 27

Let The slope of line be m

So , The slope with two points is given as equation

m = \frac{y_2 - y_1}{x_2 - x_1}

Or, m =  \frac{27 - 15}{10 + 7}

Or, m =  \frac{12}{17}

Hence The slope of line for given points is   \frac{12}{17} .  Answer

Dimas [21]

Answer: <em>1=60°</em>

Step-by-step explanation:

<em>First, let's take our given angle of 30°</em>

<em>30° is in a right triangle, so the angles must be 90°, 60°, and 30°</em>

<em>Now the angle that is 45° makes angle 1 congruent to angle 60°</em>

<em>Meaning angle 1 is </em><em>60°</em>
