1. Un edificio proyecta una sombra que mide 8 m de largo (Fig. 1.32). Se sabe que
la línea que va desde la punta de la sombra proyectada hasta el sol forma un án-
gulo de 30º con respecto del piso; y si a 1.5 m de distancia de donde termina la
sombra del edificio se alza una vara vertical (apoyada en el piso) de 50 cm de alto
cuyo extremo superior coincida con la línea mencionada:
¿Cuál es la altura del edificio?
Answer:
El edificio tiene aproximadamente 2,67 metros de altura
Step-by-step explanation:
La información proporcionada son;
La longitud de la sombra proyectada por el edificio = 8 m
El ángulo formado por la línea que va desde la punta de la sombra al Sol = 30 °
La ubicación del poste vertical desde la punta de la sombra = 1,5 m
La altura del poste vertical = 50 cm = 0,5 m
Por tanto, tenemos por triángulos semejantes formados por la punta de la sombra, la altura del poste vertical y la altura, h, del edificio la siguiente relación;
Bronceado (30 °) = h / 8 = 0,5 / 1,5
h = 8 × 0.5 / 1.5 = 8/3 m = ≈ 2.67 metros
La altura del edificio es de aproximadamente 2,67 metros.

What is the multiplicative identity of the complex number -4 + 8i?
A. 0
B. 1
C. - 4 + 8i
D. 4-8i
Answer:
1
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
its 1
for those of you that don't understand, when you multiply a complex number by its multipicatuive identity, in this case -4+8i, you would multiply both the top and the bottom by -4-8i which is actually the value one since we cannot actually change the whole value of the number. By multiplying it by "1" we get the same value just without the imaginary number .

How to know or understand easly variable which number will be in place alphabet for example, in the equation 2x + 3 = 11
Answer:
Step-by-step explanation:
a variable can have any value depending upon the equation
for example,
in 2x + 3 = 11
2x = 11 - 3
2x = 8
x = 8 / 2
x = 4
Hope this helps
plz mark as brainliest!!!!!!!
Step-by-step explanation:
Hey there!
Variables have the unknown value.
If you want to find or know value from the equation easily, you have to simply solve the equation.
For your example;
2x+3=11
Now, solve it to get value of variable 'x'.
2x = 11-3
2x = 8
[tex]x = \frac{8}{2} [/tex]
Therefore the value of variable 'x' is 4.

Solve from question 1 to 10 ( I NEED THIS ASAP! TY )
Answers:
1. 65 + x = 90
x =25
2. 51 + x = 180
x =129
3. 107 + x = 180
x = 73
y = 107
z = 73
4. angle + 13 = 180 (supplementary means 180)
angle = 167
5. angle + 38 = 180 (supplementary means 90)
angle = 52
6. (5x + 9) + (3x +11) = 180
8x + 20 = 180
8x = 160
x = 20
angle 1 = 109 angle 2 = 71
7. 17x + 1 = 20x - 14
1 = 3x - 14
15 = 3x
5 = x
angle 1 = 86 angle 2 = 86
8. (3x + 3) + (10x - 4) = 90
13x -1 = 90
13x = 91
x = 7
angle 1 = 24 angle 2 = 66
9. p = 2q - 3; q + p = 180
p = 2(180 - p) - 3
p = 360 - 2p - 3
3p = 357
p = 119
______________
q + (119) = 90
q = 61
10. b = 3c + 2; b + c = 90
b = 3(90 - b) + 2
b = 270 - 3b + 2
4b = 272
p = 68
______________
c + (68) = 90
q = 22

solve the following equation: x2-5=7
Answer:
x= 6
Step-by-step explanation:
Step 1: Write equation
2x - 5 = 7
Step 2: Solve for x
Add 5 to both sides: 2x = 12
Divide both sides by 2: x= 6
Step 3: Check
Plug in x to verify if it's a solution.
2(6) - 5 = 7
12 - 5 = 7
7 = 7
