You would use the law of sines since we are given the hypotenuse and the opposite side. 28 is opposite the angle we are looking for. 40 is directly across from the right angle making it a hypotenuse.
Sin X/1 = 28/40
sin^-1 (28/40) = 44.427004

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

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 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

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

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
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
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.

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
