*the diagram of the Russian stringed instrument is attached below.

Answer/Step-by-step explanation:

To show that the traingular parts of the two balalaikas instruments are congruent, substitute x = 6, to find the missing measurements that is given in both ∆s.

Parts of the first ∆:

WY = (2x - 2) in = 2(6) - 2 = 12 - 2 = 10 in

m<Y = 9x = 9(6) = 54°.

XY = 12 in

Parts of the second ∆:

m<F = 72°

HG = (x + 6) in = 6 + 6 = 12 in

HF = 10 in

m<G = 54°

m<H = 180 - (72° + 54°)

m<H = 180 - 126

m<H = 54°

From the information we have, let's match the parts that are congruent to each other in both ∆s:

WY ≅ FH (both are 10 in)

XY ≅ GH (both are 12 in)

<Y ≅ <G (both are 54°)

Thus, since two sides (WY and XY) and an included angle (<Y) of ∆WXY is congruent to two corresponding sides (FH and GH) and an included angle (<G) in ∆FGH, therefore, ∆WXY ≅ ∆FGH by the Side-Angle-Side (SAS) Congruence Theorem.

This is enough proof to show that the triangular parts of the two balalaikas are congruent for x = 6.

Answer:

Step-by-step explanation:

There are two polygons. The larger one has three times as many sides as the smaller one. Its angle sum is four times as big. How many sides does the smaller polygon have? (Need full solution)?

“Three times as many sides” means the larger polygon has a multiple of 3 sides. 3 is the fewest sides any polygon can have, so it has not less than 9 sides.

Its angle sum is four times the smaller one’s. This applies to interior angles.

A triangle’s sum is 180. A square’s is 360. A pentagon’s is 540. Any sum will be a multiple of 180, and equal to the number of sides minus two, then multiplied by 180.

A hexagon has 6 sides, so 4×180=720 degrees sum. That part fits the triangle, but we know that can’t be the answer because 3×3=9.

So start at 9.

7×180÷4 can’t be a multiple of 180. What we need is a multiple of 3 which is 2 greater than a multiple of 4.

18 fits that description.

The 18-gon’s interior sum is 16×180=2880, divide that by 4 to get 720, which is the hexagon’s sum.

18÷6=3, so we have a solution. The smaller polygon can be a hexagon.

We should check the next one though. Multiples of 3: 21, 24, 27, 30, 33, 36, 39, 42 (every 4th multiple of 3 will be 2 more than a multiple of 4).

So the 30-gon:

28×180=5040

5040÷4=1260

1260÷180=7

7+2=9

9×3=27

Off by 3.

The 42-gon:

((((((42–2)×180)÷4)÷180)+2)×3)=36

Off by 6. It will keep getting farther away, so we have a unique solution.

Answer:

20 mobile sets.

Step-by-step explanation:

Every mobile set costs:

40000 / 8

= 5000 Rs.

Therefore, for 100,000 Rs, the number of mobile sets that can be purchased is:

100,000 / 5000

= 20 mobile sets.

Hope this helped!

Step-by-step explanation:

The question is to combine the equations, so we should add them.

- 2x -4y = -26

+ - 3x -3y = - 12

(same signs add, different signs subtract)

-5x -7y = -38

(in the question there are two boxes at the side of the eqaution you should put (+)sign there as youre adding them)

If this question was supposed to be subtracted it would give a while different ans)

Answer:

The perimeter is 7b

Step-by-step explanation:

An isosceles triangle has exactly two sides of the same length. Suppose we have an isosceles triangle with the base as the unequal side length of b.

The perimeter of the triangle is:

P = x + x + b = 2x + b

Being x the two equal side lengths.

It's given the base b of the triangle is one-third of any of the other sides, that is:

b = 1/3 x

Or, equivalently:

x = 3b

Thus, the perimeter of the triangle is:

P = 2x + b =  = 2(3b) + b

P = 6b + b = 7b

The perimeter is 7b

Answer:

y = 4x -8

Step-by-step explanation:

The y intercept is -8 so our b term for y = mx + b is 8.

The line goes up 4 y values every one x value to the right

Answer:

y = 3x - 8

Step-by-step explanation:

To write the equation of the line in slope-intercept form, or y = mx + b, we have to find the y-intercept (b) and the slope(m).

To find the y-intercept, look at the graph at find where the line intercepts the y-axis. On this graph, the line intercepts at y = -8. Now we know the value of b.

To find the slope, look at the rise over run between two points. The line goes up by 3 every time it goes over 1. this means that our slope is 3.

Now we can input the values of the slope and the y-intercept into the equation.

y = 3x - 8

a)Scale factor is 72.

b)The area of the scale drawing is 3.75 square inches.

c)To find the area of the actual drawing, multiply the area of the scale drawing by 5184.

Length of the smaller rectangle =2.5inches

Width of the smaller rectangle = 1.5inches

So, the area of the smaller rectangle = 2.5*1.5 = 3.75 square inches.

Length of larger rectangle = 5 yards

Width of larger rectangle =3 yards

So, the area of the larger rectangle = 15 square yards = 15*36*36 = 19440 inches.

The scale factor is the factor by which the dimension of an object is enlarged.

a)Scale factor = dimension of the larger rectangle/ corresponding dimension of the smaller rectangle

Scale factor = 5 yards/ 2.5 inches

as we know that 5 yards equals 180 inches

So, scale factor = 180/2.5 = 72

b)The area of the scale drawing = 3.75 square inches.

c)Area of actual drawing/ area of scale drawing = 19440/3.75 = 5184

So, to find the area of the actual drawing, multiply the area of the scale drawing by 5184.

therefore, a)Scale factor is 72

b)The area of the scale drawing is 3.75 square inches.

c)To find the area of the actual drawing, multiply the area of the scale drawing by 5184.

Answer:

The answer is x = 6.

Step-by-step explanation:

The middle line is 2, and the leg is [tex]\sqrt{13}[/tex]. We can use the pythagorean theorem and use [tex]\sqrt{13}[/tex] as the hypotenuse and have 2 be a leg.

[tex]a^{2} + b^{2} = c^{2} \\\\2^{2} + b^{2} = \sqrt{13}^{2}[/tex]

[tex]4 + b^{2} = 13\\\\b^{2} = 9\\b = 3[/tex]

Since we know one of the bottom parts of x is 3, and the other triangle is the same as the on we solve, we do 3 + 3 which is 6. 6 is equal to x.

Answer:

x = 2 .

Step-by-step explanation:

Given  : If h(x) = 5 for the function h(x) = 2x + 1, .

To find : what is the value of x?  

Solution : We have given

h(x) = 5 for the function h(x) = 2x + 1,

Now plug the h(x) = 5.

2x + 1 = 5 .

On subtracting both sides by 1

2x  = 5 -1 .

2x = 4

On dividing both sides by 2 .

x = 2 .

Therefore, x = 2 .
