On the packaging for a triangular sail, the edge measurements for the sail are listed as 7ft x 15ft x 17ft without unfurling the sail, you want to determine if the sail forms a right triangle, an acute triangle or an obtuse triangle

To use the AA postulate directly, you need to show that two corresponding angles are congruent. In order to show that here, you must calculate the value of one of the missing angle measures. Either of the missing angles can be found by invoking the fact that the sum of angles in a triangle is 180°.

After finding either missing angle, you can show that the measures of two angles in one triangle are identical to the measures of two angles in the other triangle, hence the triangles are similar by the AA postulate.

Answer:

I wrote the answer below :)  hope it makes sense

Step-by-step explanation:

The Angle-Angle Similarity postulate can be used to prove that these two triangles are similar. To demonstrate I will use an example, and try to make sense to the reader. on triangle ABC, the 2 angles that are given to us are 32 degrees and 49 degrees. Since all triangles have an angle sum of 180 degrees, the missing degree would have to be 99 degrees. Same for the triangle A'B'C'. The 2 angles given are 99 degrees and 49 degrees, which means the missing angle has to be 32 degrees. Therefore, the triangles are similar.

I just took the test and this is correct.

The area of the sector of a circle with diameter 34 feet and an angle of π/5 radians is approximately 9.0095 square feet.

To find the area of the sector of a circle, we need to use the formula A = πr2θ/360, where A is the area, r is the radius, and θ is the angle in radians. The given diameter is 34 feet, so the radius is 17 feet. The angle is π/5 radians. Plugging these values into the formula, we get A = π(17)2(π/5)/360. Simplifying, we find A = 9.0095 square feet. Rounded to four decimal places, the area of the sector is 9.0095 square feet.

Step-by-step explanation:

Translation moves each point the same amount in the same direction. Essentially, the original segment becomes the side of a parallelogram, whose other side is the image, and whose ends are the vectors specifying the translation.

In the attachment, we have designated (a, b) as point A, and (c, d) as point B. We had to choose specific values for these in order to plot them, but the description of the effect of translation applies no matter what the point coordinates are chosen to be.

look at the shaded right-angled triangle on the left

8 is the hypotenuse n a is opposite to the 40-degree angle

by definition, sin = opposite side / hypotenuse

so sin40=a/8

rearranging a=8sin40

Two right-angled triangles share a common side with length a.

For the inverted triangle on the left, a is the opposite side to the 40-deg angle.

Its longest side, hypotenuse, is 8cm.

Use the sine function, sin40 = opposite/hypotenuse = a/8

Multiply 8 on both sides, a = 8sin40

Answer:

1. Put the numbers in order.

2. Cross off high/low pairs.

3. Add the leftover numbers.

4. Divide the sum by 2.

Step-by-step explanation:

We know that the median represent the middle value in a data which gives the center of the measure.

Whenever we calculate the median of a data the first step we need to follow is to arrange the a data in either ascending or descending order.

After that choose that center-most data value (in odd number of data value) or calculate the mean of the center-most 2 numbers ( if even) which will be the median of the  data.

Given data: 24, 16, 23, 30, 18, 29

Number of numbers = 6 (even)

1. Put the numbers in order.

16,18,23,24,29,30

2. Cross off high/low pairs., we left with the numbers :-

23,24

3. Add the leftover numbers.

23+24=47

4. Divide the sum by 2.

Answer:

A.

Step-by-step explanation:

f(3) = -9 for the function [tex]\( y = f(x) = -3x \) when \( x \) is 3.[/tex]

To find f(x) when ( x ) is 3 for the given function [tex]\( y = f(x) = -3x \),[/tex] you substitute 3 for ( x ) in the function:  [tex]\[ f(3) = -3 \times 3 \][/tex]

Now, calculate the value: [tex]\[ f(3) = -9 \][/tex]

Therefore, when ( x ) is 3, f(x) is -9 for the function [tex]\( y = f(x) = -3x \).[/tex]

In more detail, this means that if you plug ( x = 3 ) into the function, it will result in ( y = -9 ). The function ( y = -3x ) represents a linear relationship where the coefficient of ( x ) is -3. This indicates that for each unit increase in ( x ), ( y ) decreases by 3 units. In the specific case of ( x = 3 ), substituting this value into the function gives [tex]\( y = -3 \times 3 = -9 \).[/tex]

This kind of analysis is fundamental in understanding the behavior of linear functions. It provides insight into how the function's output (y) changes in response to changes in the input ( x ). In this case, when ( x ) increases by 1, ( y ) decreases by 3, leading to the slope of -3 in the function ( y = -3x ).

(a) 6% of the value of the investment is added each year. This means the value of the investment is multiplied by 1.06 each year. After 15 multiplications, the value is ...

... $3000×1.06¹⁵ ≈ $7189.67

(b) The interpretation of this result is ...

... After 15 years, the investment is worth $7189.67.

The future value of a $3000 investment at an annual interest rate of 6%, compounded annually for 15 years, is approximately $8093.97. This means that the original sum will grow to this amount after the set period.

To find the future value of an investment, we use the formula for compound interest which is A = P(1 + r/n)^(nt). Where:

Given are P = $3000, r = 6%/100 = 0.06 (annually), n = 1 (since it's compounded annually), and t = 15 years. Plugging these into the formula, we get A = $3000(1 + 0.06/1)^(1*15) = $3000(1.06)^15 = $8093.97.

Interpreting this, it means that investing $3000 at 6% compounded annually would grow to approximately $8093.97 after 15 years.

Part A:

[tex]25x+15y=650[/tex]

As it is given, Sharla can make 40 necklace so,

[tex]25x+15(40)=650[/tex]

Or it could be 25x=650 and 15y=650

Let x be the bigger number and y be the smaller number.

One number is 11 more than twice another number. Thus,

x = 2y + 11

The sum of the numbers is twice their difference, thus,

x + y = 2(x-y), which simplifies to:

x + y = 2x - 2y

3y = x  (Now plug this back to the first equation:

3y = 2y + 11, and solve:

y = 11

Plug in y = 11 to the first equation:

x = 2(11) + 11 = 22 + 11 = 33

Thus the numbers are: x = 33, y = 11.
