On his math test, Balavan wrote that a four-sided polygon that has at least two right angles must be a rectangle or a square. Denna wrote that a four-sided polygon needs at least three right angles to be a rectangle or a square. Who is right? Explain your answer.

Answers

Answer 1

Answer:

a quadrilateral with 2 right angles could be a trapezoid so balavan is wrong.   because if 3 angles are right angles the the  fourth angle might also be a right angle and has to be a square or rectangle so denna is right  

Step-by-step explanation:

Answer 2

Answer:

The sum of the angles in a quadrilateral is 360°, and a rectangle or square has four 90° angles.

A quadrilateral can be formed with two right angles and two angles that are other measures.

If three angles are 90°, the total is 270°, so the fourth angle is 90°.

Step-by-step explanation:

those are the 3 things you need

Answer:

Step-by-step explanation:

No se si esto deberia ser mas dificil pero aqui voy:

Pregunta 1.

27 - 15 = 12

El numero es 12

Pregunta 2.

27 - 5= 22 dividido 2 = 11

El numero que pensastes es 11

Pregunta 3.

32 - 8 = 24 dividido 2 = 12

El tiene 12 años

Use el metedo reversa.

Construyendo y resolviendo las ecuaciones, encontramos que:

1. El numero es 12.2. El numero es 11.3. La edad de Juan es 12.

---------------

Ejercicio 1

El número es x.Sumando 15, tenemos x + 15 Obtuve 27, entonces:

[tex]x + 15 = 27[/tex]

[tex]x = 27 - 15 = 12[/tex]

El numero es 12.

Ejercicio 2

El número es x.Multiplicando por 2, tenemos 2x. Sumando 5, tenemos 2x + 5.Obtuve 27, entonces:

[tex]2x + 5 = 27[/tex]

[tex]2x = 22[/tex]

[tex]x = \frac{22}{2}[/tex]

[tex]x = 11[/tex]

El numero es 11.

---------------

Ejercicio 3

La edad es x.Doble de la edad es 2x.Sumando 8, tenemos 2x + 8.Obtuve 32, entonces:

[tex]2x + 8 = 32[/tex]

[tex]2x = 24[/tex]

[tex]x = \frac{24}{2}[/tex]

Find the value of x if the measure of angle 1 = 11x - 9 and the measure of angle 5 = 7x + 9

Answers

Answer:

x = 10

Step-by-step explanation:

Lett angle 1 and angle 5 lie on the same straight line. This shows that they are supplementary

Hence;

<1 + <5 = 180

11x - 9 + 7x + 9  = 180

18x = 180

x = 180/18

x = 10

Hence the value of x is 10

The diameter of a planet is about 25,660 mi. The diameter of the planet's moon is about 35% of the diameter of the planet. What percent of the volume of the planet is the volume of its moon?
The volume of the planet's moon is % of the volume of its planet.
(Round to the nearest whole number as needed.)

Answers

Answer:

4%

Step-by-step explanation:

Volume of sphere

v = (4/3)πr^3

Volume moon/ volume planet

We don't actually need the numeric value of the radius

just the 35% ratio

Radius of moon = .35 radius of planet

Vm/ Vp = (4/3)π(.35r)^3 / (4/3)π(r)^3

Cancel like terms

Vm / Vp = .35^3

Vm / Vp = 0.042875

Expressed as a percentage

Vm / Vp = 4.2875%

Rounded

Vm / Vp = 4%
