Q19 - x = 7
Q20 - x = 24
Step-by-step explanation:
Q19.
75 + x + 8 = 90°
83 + x = 90°
x = 90 - 83
x = 7
{CHECK: 75 + 7 + 8 = 90°}
Q20.
3x - 6 + x = 90°
4x - 6 = 90°
4x = 96
x = 96 / 4
x = 24
{CHECK: 3(24) - 6 + 24 = 90°}
hope this helps...
have a great day ahead ;)

The midpoint of AB is M(- 2, 1) . If the coordinates of (1, - 2) , what the coordinates of B?
Answers
Answer:
(-5, 4)
Step-by-step explanation:
Finding the X of B
-2 = x2+x1/2
-2 = x2+1/2 (substituted X co-ord of A into x1)
-4=x2+1 (multiplied both sides by 2)
-5=x2 (brought 1 to the other side)
Finding the Y of B
1 = y2+y1/2
1 = y2 - 2/2 (substituted Y co-ord of A into y1)
2 = y2 -2 (multiplied both sides by 2)
4 = y2 (brought 2 to the other side)

Answers
Answer:
Step-by-step explanation:
There are 2 repeating digits in .64(with a line over both of those numbers). The value to multiply on to both sides will be 100. To find the fraction that represents the repeating decimal, there are steps to follow. First, make sure the decimal is just before the repeating decimals. It is, so we are good there. Next, move the decimal over how ever many places to get it right after the repeating numbers. That means moving the decimal 2 places to the right. That's the same as multiplying by 100:
100x = 64.6464
What we have now is a system with the equation above and
x = .6464
We subtract them:
100x = 64.6464
- x = .6464
to get
99x = 64. Solving for x:
x = 64/99
That's how you change a repeating decimal to a fraction.

Line segment EG is partitioned by point F in the ratio 1:3. Point E is at E (0, 4), and point F is at (1, 3). What are the coordinates of point G? (−1, 5) (2, 2) (3, 1) (4, 0)
Answers
Answer:
(4,0)
Step-by-step explanation:
Line segment EG is partitioned by point F in the ratio 1:3.
This means that:
[tex]F - E = \frac{1}{4}(G - E)[/tex]
We use this equation to find both the x-coordinate and the y-coordinate of point G.
x-coordinate:
x-coordinate of E: 0
x-coordinate of F: 1
x-coordinate of G: x
Then
[tex]F - E = \frac{1}{4}(G - E)[/tex]
[tex]1 - 0 = \frac{1}{4}(x - 0)[/tex]
[tex]1 = \frac{x}{4}[/tex]
[tex]x = 4[/tex]
y-coordinate:
y-coordinate of E: 4
y-coordinate of F: 3
y-coordinate of G: y
Then
[tex]F - E = \frac{1}{4}(G - E)[/tex]
[tex]3 - 4 = \frac{1}{4}(y - 4)[/tex]
[tex]-1 = \frac{y-4}{4}[/tex]
[tex]y - 4 = -4[/tex]
[tex]y = 0[/tex]
What are the coordinates of point G?
x = 4, y = 0, so (4,0).

Draw a graph of the linear equations x – 4y + 10 = 0 and x + 4y – 10 = 0. Find the coordinates of the vertices of the triangle formed by these lines along with the X-axis
Answers
Step-by-step explanation:
x-14y=0
x=0/14y
x=14y
14y
The second equation crosses the x axis at x + 4 x 0 - 10 = 0 => x = +10
Adding the equations together gives 2x = 0 => x = 0
0 + 4y - 10 = 0 => 4y = 10 => y = 2.5
The vertices of the triangle formed by the two lines and the x axis are (-10, 0) (10, 0) and (0, 2.5)

A) En un videojuego el número de pruebas que hay que superar es el doble de las del nivel anterior, si en el nivel 1 hay dos pruebas, ¿Cuántas habrá en el nivel 5? ¿y en el 9? ES PARA MAÑANAAAAA
Answers
Answer:
En el nivel 5 habrá 32 pruebas mientras que en el nivel 9 habrá 512 pruebas.
Step-by-step explanation:
En un videojuego en el nivel 1 hay 2 pruebas.
El número de pruebas que hay que superar es el doble de las del nivel anterior. Entonces en el nivel 2 se deben superar 4 (2 pruebas del nivel 1*2, el doble) pruebas, mientras que en el nivel 3 hay que superar 8 pruebas (4 pruebas del nivel 2*2, el doble).
Una sucesión es una secuencia ordenada de números. Si observamos en este caso, la sucesión que se forma para calcular el número de pruebas es 2ⁿ, donde n es el número de nivel en el videojuego.
Entonces, por ejemplo, en:
el nivel 1: 2ⁿ= 2¹= 2 pruebasel nivel 2: 2ⁿ= 2²= 4 pruebasel nivel 3: 2ⁿ= 2³= 8 pruebasEntonces, para calcular la cantidad de pruebas en el nivel 5 se realiza el cálculo:
2ⁿ= 2⁵= 32 pruebas
mientras que para calcular la cantidad de pruebas en el nivel 5 se realiza el cálculo:
2ⁿ= 2⁹= 512 pruebas
Entonces, en el nivel 5 habrá 32 pruebas mientras que en el nivel 9 habrá 512 pruebas.
Sabiendo como cambia el número de pruebas por nivel, veremos que en el nivel 5 hay 32 pruebas y en el nivel 9 hay 512 pruebas.
Sabemos que la cantidad de pruebas que hay que superar en cada nivel es el doble de las que hay en el nivel anterior.
Entonces, esto es una serie geometrica, que se puede escribir como:
[tex]A_n = A_1*2^{n - 1}[/tex]
Donde A₁ es la cantidad de pruebas en el primer nivel, que sabemos que son 2.
Entonces escribimos:
[tex]A_n = 2*2^{n-1} = 2^n[/tex]
En el nivel 5 tenemos n = 5, entonces la cantidad de pruebas que hay en e nivel 5 esta dado por:
[tex]A_5 = 2^5 = 32[/tex]
Es decir, hay 32 pruebas en el nivel 5.
Para el nivel 9 tenemos n = 9, entonces hay:
[tex]A_9 = 2^9 = 512[/tex]
Hay 512 pruebas en el nivel 9.

A diver was at 58m below sea level.The diver swam up 4m every 12 seconds. Where is the location of the diver after 2 minutes?
Answers
Answer:
18 metres below sea level.
Step-by-step explanation:
Since the diver swims up 4 metres every 12 seconds, that means the diver swims up 4 * (60/12) metres = 20 metres every minute. Therefore, he will have swum up 20 * 2 = 40 metres after 2 minutes. Factoring in the diver's original position, -58m, we can calculate his position to be -58 + 40 metres = -18 metres, meaning 18 metres below sea level.

We know angle M also is x because the sides are the same length
The sum of the angles of a triangle add to 180
x+x+32 = 180
Combine like terms
2x+32 =180
Subtract 32 from each side
2x = 180-32
2x =148
Divide by 2
2x/2 =148/2
