Answer:
The polygon has 43 sides . The polygon can be called 43 - gon or tetracontakaitrigon.
Step-by-step explanation:
In a regular polygon all the sides are equal and also all the angles are equal. The sum of the interior angle of a polygon can be calculated with the following formula;
sum of interior angle = (n−2) × 180°
where
n = number of sides
The sum of the interior angle should be less than 7500 and greater than 7201.
sum of interior angle = (n−2) × 180°
less than 7500 and greater than 7201 = (43 - 2) × 180
less than 7500 and greater than 7201 = 41 × 180
less than 7500 and greater than 7201 = 7380

The polygon has 43 sides . The polygon can be called 43 - gon or tetracontakaitrigon.
Just took the test. A is the right answer.
Let one acute angle be X and one be Y
X+Y=90 -------Eq.1
2X+12=Y
2X-Y=-12------Eq.2
solving eq 1&2 we get,
3x=78
∴X=26
substituting value X in equation.1
X+Y=90
Y=90-26
∴Y=64
⇒answer:- X=26°
Y=64°
B is the answer because you have to math it
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>
