Step-by-step explanation:

Congruent triangles are also frequently employed in architectural designs, carpet patterns, stepping stone patterns, and geometric art.

The following are the two most typical instances of this: Equilateral triangles are used to make truss bridges, which are built on both sides.

Congruence :

If all three corresponding sides and all three corresponding angles are equal in size, two triangles are said to be congruent. Slide, twist, flip, and turn these triangles to create an identical appearance. They are in alignment with one another when moved. A term used to describe an object and its mirror counterpart is congruence. If two things or shapes superimpose on one another, they are said to be congruent. They are identical in terms of size and shape. Line segments having the same length and angles with the same measure are congruent in the context of geometric figures.

The guy wire must be about 55 feet long and the slope of the guy wire, expressed as a fraction is 25/11.

We can use the Pythagorean Theorem to find the length of the guy wire. Let's call the length of the guy wire "g".

g^2 = 50^2 + 22^2

g^2 = 2500 + 484

g^2 = 2984

g ≈ 54.65

So the guy wire must be about 55 feet long.

The slope of the guy wire is the ratio of the vertical distance it covers to the horizontal distance it covers. In this case, the vertical distance is 50 feet (the height of the pole) and the horizontal distance is 22 feet. So the slope is

50/22 = 25/11

Therefore, the slope of the guy wire is 25/11.

The probability that the rate of return of this investment is greater than 10 percent is approximately 0.9214, or 92.14%.

1. Calculate the expected value and variance of the total return:
Since X1 and X2 are independent, we can simply add their means and variances.
Expected Value (E) = Mean of X1 + Mean of X2 = 60 + 60 = 120
Variance (V) = Variance of X1 + Variance of X2 = 25 + 25 = 50

2. Determine the 10 percent rate of return:
A 10 percent return on an initial investment of 100 would yield a total of 110 (100 + 10% * 100).

3. Calculate the Z-score:
The Z-score represents how many standard deviations away the desired value (110) is from the mean (120). To calculate the Z-score, we use the following formula:
Z = (X - E) / sqrt(V)
Z = (110 - 120) / sqrt(50)
Z = -10 / sqrt(50)
Z = -10 / 7.07
Z = -1.414

4. Find the probability:
Now, we need to find the probability that corresponds to the Z-score of -1.414. Using a standard normal distribution table or an online calculator, we find that the probability of a Z-score less than -1.414 is approximately 0.0786.

5. Calculate the probability of a rate of return greater than 10 percent:
Since we want the probability of a rate of return greater than 10 percent, we need to find the complement of the probability we just calculated.
Probability (rate of return > 10%) = 1 - P(Z < -1.414)
Probability (rate of return > 10%) = 1 - 0.0786
Probability (rate of return > 10%) = 0.9214

Diego's mistake was that he forgot to distribute the 1/3 across the parentheses, so he should have solved the equation like this:  1/3x + 5 = 3, which can be rearranged to x = 14.

Given equation is 1/3(x+15)=3. For solving this equation we have to simplify this equation as follows:

Multiplying both sides by 3 to eliminate the fraction; we get(x + 15) = 9. Distributing the number 1/3 to both terms inside the parenthesis we get (x/3) + 5

Combining like terms we get(x/3) = -2. Multiplying both sides by 3 we get x = -6.

the solution to the given equation is x = -6.So, Diego's mistake was that he didn't eliminate the fraction first.

The error in finding the measure of one exterior angle of a regular polygon lies in using the formula 360°/n, where n is the number of sides of the polygon.

The formula 360°/n is used to find the measure of each exterior angle of a regular polygon. It is based on the idea that the sum of all exterior angles of any polygon is always 360 degrees. However, this formula assumes that the polygon has internal angles of 180°, which is true only for regular polygons.

The error occurs when this formula is applied to a non-regular polygon, as non-regular polygons have varying internal angles. Using the formula 360°/n for a non-regular polygon will give incorrect results because the internal angles are not all equal.

For regular polygons, each exterior angle is indeed 360°/n, and the sum of all exterior angles will be 360 degrees. However, for non-regular polygons, this formula cannot be used, and the measures of exterior angles must be calculated differently based on their internal angles and sides.

the weight of the crackers originally in the box was 120/23 pounds.

Let the weight of the entire box be x pounds. Now, Roger served 5/8 pound of crackers, which was 2/3 of the entire box.

Therefore, the weight of the crackers left in the box = (1 - 2/3) x = 1/3 xSince the crackers served by Roger was 5/8 pound, the weight of the crackers left in the box = x/3, then we can set up the following equation to find the value of x:5/8x + 1/3x = x

Multiplying the equation by 24 (the least common multiple of 8 and 3) on both sides gives us:

15x + 8x = 24x

Therefore, 23/24 x = 5/8 pound of crackers served by Roger.So, x = (5/8) x (24/23) pounds = 15/23 pounds

To solve the given question, let us suppose that the weight of the entire box of crackers is x pounds. Now, the given information is that Roger served 5/8 pound of crackers which was 2/3 of the entire box.

Therefore, the weight of the crackers left in the box = (1 - 2/3) x = 1/3 x.Now, we need to find out the original weight of the crackers in the box, which is the value of x.

To do that, we can set up an equation as follows:5/8x + 1/3x = xMultiplying both sides by the least common multiple of 8 and 3, which is 24, we get:15x + 8x = 24x

Simplifying further, we get:23x = 120x = 120/23 poundsThis is the weight of the entire box of crackers.

Therefore, the weight of the crackers originally in the box was 120/23 pounds.

Where:

Based on the information provided, we have the following equation of a circle:

x² + y² – 2x – 8 = 0      ......equation 2.

In order to determine the true statements, we would have to rewrite the equation in standard form and then factorize by using completing the square method:

x² – 2x + y² = 8 = 0

x² – 2x + (2/2)² + y² = 8 + (2/2)²

x² – 2x + 1 + y² = 8 + 1

Step-by-step explanation:

From the above question,

P = Principal = $200

R = Interest rate = 20%

T = Time in years = 3 years

n = Number of times interest is compounded = Annually = 1

First, convert R as a percent to r as a decimal

r = R/100

r = 20/100

r = 0.2 rate per year,

Then solve the equation for A

The formula =

A = P(1 + r/n)^nt

A = 200.00(1 + 0.2/1)^(1×3)

A = 200.00(1 + 0.2)^(3)

A = $345.60
