What is the result of adding these two equations?

Mathematics

timofeeve [1]3 years ago

Answer:

the result of adding these two equations is

3x = 14

Step-by-step explanation:

We are given two equations

5x − y  = 6          eq. 1

−2x + y = 8        eq. 2

Add the like terms together

5x - 2x = 3x

− y + y = 0

6 + 8 = 14

So the result of adding these equations is

3x + 0 = 14

3x = 14

Bonus:

The value of x is

3x = 14

x = 14/3

Cómo puedo hallar la longitud de un lado de un triángulo usando el teorema del ángulo de 30°
Elza [17]

En un triángulo rectángulo con ángulos de 30° -60° -90°, para encontrar la longitud de un lado, debes encontrar la longitud de la hipotenusa.

<h3 /><h3>¿Cómo encontrar la longitud de la hipotenusa?</h3>

Es necesario encontrar la longitud del cateto opuesto al ángulo de 30°, también conocido como cateto menor, y luego multiplicarlo por 2, descubriendo así el cateto de la hipotenusa, utilizando la fórmula del teorema de Pitágoras:

  • a²+b²=c²

Por lo tanto, puedes usar el teorema de Pitágoras para calcular la longitud del lado que falta en un triángulo rectángulo.

On a piece of paper, use a protractor to construct right triangle ABC with AB = 4 inches. , m A = 90 , and m B = 45. What statem
iris [78.8K]

Answer:

Step-by-step explanation:

Angle A = 90°

Angle B = 45°

According to the angle sum property

Angle A + Angle B + Angle C = 180°

90° + 45° + Angle C = 180°

Angle C = 45°

As the two angles are equal so the triangle is right angle isosceles triangle.
