Hi there! We can find the value of x by using this equation.
[tex] \large \boxed{tanx = \frac{19}{23} }[/tex]
If you remember, tanx = opposite/adjacent. We focus on the angle x currently.
Now that you might wanna ask if there is a value of x that makes 19/23. The answer is yes but in decimal.
[tex] \large{arctan( \frac{19}{23} )} = x[/tex]
You might wanna put arctan(19/23) in a calculator since it's not really possible to get the square root like value by yourself.
arctan(19/23) is 0.69
Then we round up and get 0.7
Hence, the value of x ≈ 0.7
Answer
x ≈ 0.7 (rounded)Questions can be asked through comment.
Hope it helps, and Happy Learning! :)

Answer:
(x - 8)² = 14
Step-by-step explanation:
Given
x² - 16x + 26 = - 24 ( subtract 26 from both sides )
x² - 16x = - 50
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 8)x + 64 = - 50 + 64
(x - 8)² = 14
A field in the shape of a quadrilateral has a perimeter of 166 m. A fence is being built along the field's perimeter. Determine the length of fencing needed for each side of the field.
Answers
Answer:
3x - 4 = 32
2x = 24
5x + 10 = 70
4x - 8 = 40
Step-by-step explanation:
Please find the complete question in the attached image
Perimeter = sum of sides of the quadrilateral
166 = 4x - 8 + 5x + 10 + 2x + 3x - 4
166 = 14x - 2
combine like terms
166 + 2 = 14x
168 = 14x
x = 12
substitute for x in each of the sides
3x - 4 = 3(12) - 4 = 32
2x = 2 x 12 = 24
5x + 10 = 5(12) + 10 = 70
4x - 8 = 4(12) - 8 = 40
Mateo compró un artefacto gastando los 3/7 de su dinero, quedándole 360 soles, ¿Cuál era el dinero que tenía Mateo al inicio?
Answers
Answer:
840 soles
Step-by-step explanation:
Sea la cantidad de dinero que Mateo tenía al principio = x
Mateo compró un artefacto gastando 3/7 de su dinero, dejándole 360 soles,
Por eso,
3/7 × x = 360 soles
3x / 7 = 360 soles
Multiplicar cruzada
3x = 7 × 360 soles
x = 7 × 360 soles / 3
x = 840 soles
Por tanto, el dinero que tenía Mateo al principio es de 840 soles

Calculate the marked price (original price) if
a. After 25% discount, the price of an article is Rs 7500,
Answers
Answer:
Step-by-step explanation:
let original price of an article be x
marked price(price after discount )=Rs 7500
discount%=25%
discount =discount % of cost price
=25/100*x
=25x/100
=x/4
Mark price=original price-discount amount
Rs 7500=x-x/4
Rs 7500=4*x-x/4
Rs 7500*4=4x-x
Rs 30000=3x
Rs 30000/3=x
Rs10000=x
therefore original price of an article is Rs 10000.

Greggory is trying to raise money for his school's football team by selling T-shirts and sweatshirts. The football team will get $3 for each sweatshirt sold and $4 for each T-shirt sold. The rest of the money goes to paying for the items to be sold. Greggory manages to sell a total of 121 items and the team ends up getting $406.
Answers
# of t-shirts sold = y = 43
We know:
x + y = 121
3x + 4y = 406
Solve the first equation for x in terms of y, then substitute that into the second equation.
x = 121 - y
3(121 - y) + 4y = 406
363 - 3y + 4y = 406
y + 363 = 406
y = 43
Then solve for x
x = 121 - y
x = 121 - 43
x = 78
Check the math:
3(78) + 4(43) = 234 + 172 = 406
A loading tempo can carry 482 boxes of biscuits weighing 15kg each, whereas a van can carry 518 boxes each of the same weight. Find the total weight (in kg) that can be carried by both the vehicles.
Answers
Answer:
Tempo = 7,230kg
Van = 7,770kg
Step-by-step explanation:
FOR THE TEMPO
boxes of biscuits = 482
Each weight = 15kg each
= 482 x 15kg
= 7,230kg
FOR THE VAN
boxes of biscuits = 518
as written in the question that Each box have the same weight as in the tempo so it is = 15kg Each
= 518 x 15kg
= 7,770kg
A ladder is placed 10 feet away from a tree. The length of the ladder is 25 feet. Find the height of the tree?
STEP BY STEP PLS
Answers
Answer:
23ft approx
Step-by-step explanation:
Given data
Distance from tree= 10ft
Length of ladder= 25ft
We can find the height of the tree by applying the Pythagoras theorem
z^2= x^2+y^2
z= The height of the ladder
x= The distance from the tree
y= The height of the tree
25^2= 10^2+ y^2
625=100+y^2
625-100=y^2
525=y^2
y= √525
y= 22.91
Hence the height of the tree is 23ft approx
What is the first step you will use to solve this equation:
4x +2 = 7x - 13
Answers
1. Subtract 2 from both sides of the equation
4x + 2 = 7x - 13
4x + 2 - 2 = 7x - 13 - 2
2. Simplify
4x + 2 - 2 = 7x - 13 - 2 -----> 4x = 7x - 13 - 2 -----> 4x = 7x - 15
3. Subtract 7x from both sides of the equation
4x = 7x - 15
4x - 7x = 7x - 15 - 7x
4. Simplify
4x - 7x = 7x - 15 - 7x -----> -3x = 7x - 15 - 7x -----> -3x = -15
5. Divide both sides of the equation by the same term
-3x = -15
-3x/-3 = -15/-3
6. Simplify
-3x/-3 = -15/-3
x = -15/-3
x = 5
7. Solution
x = 5
