2 rectas se cortan formando 4 ángulos iguales ¿cuanto mide cada uno?

Answers

Answer 1

Answer:

Cada ángulo igual es recto, es decir, mide 90°

Step-by-step explanation:

Intersección de dos rectas

Cuando dos rectas no paralelas se intersectan, forman en el punto de corte 4 ángulos iguales de a pares, es decir, dos pares de ángulos congruentes.

La suma de todos los ángulos formados es invariablemente 360°.

En general, siendo a y b dos ángulos adyacentes formados por el cruce, se cumple que:

a + b = 180°

Y la suma de todos los ángulos es el doble de lo anterior:

2a + 2b = 360°

Si todos los ángulos son iguales, a=b, entonces:

4a = 360°

a = 90°

Cada ángulo igual es recto, es decir, mide 90°

Step-by-step explanation:

-√2x-5=5-x

√2x-5=-5+x

2x-5=x²-10x+25

2x-5-x²+10x-25=0

12x-20-x²=0

-x²+12x-20=0

x²-12x+20=0

x=10

Note: there is a another answer x=2 but the equality will be false if x=2 so the answer is 10

Answers

Answer:

The ordered pair is (4,6)

Step-by-step explanation:

Ordered Pairs

It's given the equation

y = x + 2

Since there are no restrictions for the values of x and y, it has infinitely many solutions, i.e. any ordered pair of values (x,y) that make true the equation is a solution.

We can pick any value for x and then calculate the corresponding value for y as follows:

For x = 4,

y = 4 + 2 = 6

The ordered pair is (4,6)

Anelle is saving to buy a guitar that costs $350. So far she has saved $105.20. She wants to buy the guitar in 18 weeks. Based on this information, which statement is true?

Answers

Answer:

Step-by-step explanation:

350-105.20= 244.80 is still needed

I don't have the statements so...

244.80/18 weeks = 13.60 She'll need to save at least $13.60 a week for 18 weeks to make up the difference.

Answer:

Step-by-step explanation:

18x + 105.2 ≥ 350

18x ≥ 244.8

x ≥ 13.6

She has to save at least $13.6 per week.

[tex]x=155[/tex]

Step-by-step explanation:

According to the definition of a linear pair:

[tex](x-25)+(50)=180[/tex]

Solve for [tex]x[/tex].

Combine like terms on the left:

[tex]x+25=180[/tex]

Subtract 25 from both sides:

[tex]x=155[/tex]

Hence, the value of [tex]x[/tex] is 155.

Answer:

x=155, the angle is 130 degrees

Step-by-step explanation:

Assuming you want to find x:

A straight line is 180 degrees so that means

x-25+50=180 add like terms together

x+25=180 subtract 25 from both sides

x=155

If you want to find the degree angle, just replace x with 155

x-25=155+25=130

Also if you want to know, yes I edited my answer as I couldn't tell if that was a + or a - in the picture. Have a nice day and happy thanksgiving!

A pile of pebbles has a weight of 95 kg.

The pebbles in the large bag weighs 45 kg more than the pebbles in the small
What is the weight of the pebbles in the large bag?​

Answers

Answer:

70kg

Step-by-step explanation:

s = small bag

b = big bag

Equations

s + b = 95

s + 45 = b

plug in

s + s + 45 = 95

2s + 45 = 95

2s = 50

s = 25

plug in to find big bag

25 + 45 = b

70 = b

Answer:

The weight of the pebbles in the large bag is 70kg.

Step-by-step explanation:

This looks like a substitution algebra problem. To do this, I’m going to mark the large bag with (L) and the small bag with the variable, (s). I will make first 2 equations to show the value. The first equation would be L=45+s. The second equation would be 95=L+s. Since L is literally 45+s, add this into the 2nd equation. This would be 95=45+s+s. You should have 95= 45+2s and you would subtract 45 from both sides then. Finally, divide 2s by 2 to get what the small bag weighs, (which is 25kg). To find the large bag’s weight, use the first equation to find the answer. L= 45+s or 25. The answer would bring us to 70 kg.

How do I solve this equation and check the solutions?

Answers

Answer: x = -10 or 2

Step-by-step explanation:

Given:

√20 - 8x = x

Step 1: Square √20 - 8x

(√20 - 8x)² = (x)²

20 - 8x = x²

Now we can solve the problem

Step 2: Move 20 - 8x to the other side

20 - 8x = x²

-20 + 8x   - 20 + 8x

0 = x² + 8x - 20

This is a quadratic equation

Step 3: Factor the quadratic equation

10(-2) = -20 and 10 - 2 = 8

So our factors are 10 and -2

(x + 10)(x - 2) = 0

Step 4: Create a FOIL equation

For this equation to be true, x would have to make either one of the parenthysis equal to zero

(x + 10)(x - 2)

x = -10 x = 2

10 - 10 equals zero, and -2 + 2 equals zero, so those are your answers.
