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>
The answer is 10 because if you round It Off it will be 5 + 10 equal 15 Sultan is the answer to your question
Answer:
Equation to find area: l*w
Unknown measurement: w = 4,700/94 = 50
Equation to find perimeter: l+l+w+w or l*2+w*2
Perimeter: 288
Hope this helps :)
Answer: 1,250
Step-by-step explanation:
Given: The total number of students in the school= 25,000
Since each class has 10 students , therefore, the number of classes in the school= 
Also, Each student takes 2 classes a day, thus the number of classes taken by total teachers in a day = 
Also, each teacher teaches 4 classes.
Then the number of teachers in the school =
Hence, the number of teachers are at Big Big School = 1,250
Solve for the first variable in one of the equations, then substitute the result into the other equation.
