third angle is 45 degrees more than that of the smallest angle. Find the measure of the LARGEST angle.
Answer: The LARGEST angle has a measure of
Answer:
The LARGEST angle has a measure of 81°
Step-by-step explanation:
Let α be the smallest angle
β be the second angle
θ be the third angle.
• One (second) angle in a triangle has a measure that is three times as large as the smallest angle.
Then
β = 3α
• The measure of thethird angle is 45 degrees more than that of the smallest angle.
Then
θ = α + 45
• We know that the sum of the interior angles of a triangle add up to 180°
Then
α + β + θ = 180
Then
α + (3α) + (α + 45) = 180
Then
5α + 45 = 180
Then
5α = 135
Then
α = 27
_______________
β = 3α = 3 × 27 = 81
θ = α + 45 = 45 + 27 = 72
Conclusion :
The LARGEST angle has a measure of 81°

Answer:
Step-by-step explanation:
2(2x-5)=3x+x-2x
4x-10=3x+x-2x
4x-10=2x
4x-10+10=2x+10
4x=2x+10
2x=10
2/2
10/2=5
x=5
The solution to the equation 2(2x-5) = 3x + x - 2x is x = 5
Given data:
To solve the equation 2(2x - 5) = 3x + x - 2x, we will simplify and solve for x.
Step 1: Distribute the 2 to the terms inside the parentheses:
4x - 10 = 3x + x - 2x
Step 2: Combine like terms on both sides of the equation:
4x - 10 = 2x
Step 3: Subtract 2x from both sides to isolate the variable x:
4x - 2x - 10 = 0
Simplifying:
2x - 10 = 0
Step 4: Add 10 to both sides to eliminate the -10 term on the left side:
2x - 10 + 10 = 0 + 10
Simplifying:
2x = 10
Step 5: Divide both sides by 2 to solve for x:
(2x)/2 = 10/2
Simplifying:
x = 5
Hence, the solution is x = 5.

The temperature drops to 15 degrees below zero. What is a real world example to make 0 in this situation?
Here are the examples that combine to make zero:
Two month ago, the temperature was 15 degrees. This morning, the temperature dropped to 15 degrees below zero.
Michael has $0 in his account. He makes a purchase of $75. Later in the day, he deposits 75 in the account.
An elevator rises to the ninth floor and she then takes the elevator from the ninth floor to the ground floor.
The parking garage is located 4 floors below ground level. But, her office is 4 floors above ground level.
What are the real world examples?
In order for the examples to combine to make zero, there has to be a positive number and a negative number. A positive number is a number that is greater than zero. A negative number is a number that is less than zero.
In order for the positive and negative number to make zero, they have to be added together. Addition is determining the total value or summing two or more numbers. Addition is one of the four basic operations in mathematics.

A rectangular piece of metal is 5 in. longer than it is wide. Squares with sides 1 in. long are cut from the four corners, and the
flaps are folded upward to form an open box. Which equation indicates that the volume of the box is 56 in.³?
The equation which shows the volume of rectangular box is w² + 5w - 56 = 0.
What is defined as the rectangle?A rectangle is a two-dimensional (2D) shape with opposite sides that are parallel as well as equal to each other and four right angles.
The breadth (width) of a rectangle is the shorter side, and the length is the longer side.
The metal's length is 5 inches longer than its width. However, we fold up 1-inch flaps on every side, resulting in a 1-inch box height and an 2-inch decrease in length and width (1 inches on each side). Because the length and width both decrease in the same amount, the length remains 5 inches longer than that of the width.Then, the equations are as follows:
l = w + 5
The height of the box will be 1 inch which is cut and folded upward.
vol = l x w x h = 56 in³
Substitute the value of l in the equation.
56 = (w + 5)(w)(1)
56 = w² + 5w
w² + 5w - 56 = 0
Therefore, the equation which represent the volume of the rectangular box on 56 in.³ is w² + 5w - 56 = 0.

Joshua purchased a game card for the arcade for a total of $20. He played three basketball hoop games for $2.25 each and two rounds of air hockey for $1.75 each. How much did he have left on the game card?
1.)$ 13.50
2.)$ 10.25
3.)$ 9.75
4.)$ 6.75
Answer:
b
Step-by-step explanation:
Joshua had $9.75 left on the game card (option 3).
Joshua's expenses on the game card can be calculated as follows:
Cost of playing three basketball hoop games = 3 games * $2.25/game
Cost of playing three basketball hoop games = $6.75
Cost of playing two rounds of air hockey = 2 rounds * $1.75/round
Cost of playing two rounds of air hockey = $3.50
Total expenses = $6.75 + $3.50
Total expenses = $10.25
Joshua originally had $20 on the game card, and he spent $10.25. To find out how much he had left, subtract his expenses from the original amount:
Amount left = $20 - $10.25
Amount left = $9.75
So, Joshua had $9.75 left on the game card.

The number of subsets formed is 67,108,864.
What is defined as the subsets?Set 1 is said to be a subset of set 2 if all of its elements are present in it. A set is a clearly defined group of numbers, alphabets, items, or any other items.
If set 1 = A,B,C and set 2 = A,B,C,D,E,F, then set 1 is a subset of set 2 because all of the elements in set 1 are also present in set 2.A subset is a subset of a larger set (another set or the same set). To symbolize a set A as a subset of a larger set B, use the set notation: A ⊆ B.The number of subsets of an n-element set is 2ⁿ.
As a result, the formula for determining the number of subsets of the a set with 'n' components is 2ⁿ.
For the given question;
A={x:x is letters of the alphabet}
Thus, the n = 26 (total letter is English alphabet).
Total subsets = 2ⁿ
Total subsets = 2²⁶ = 67,108,864.
