What is a drawing scale?

Given scale is,

19:8

Therefore,

To determine the, actual length,

[tex]\frac{19}{8} =\frac{38}{actual\ length}[/tex]

⇒ actual length = [tex]\frac{38}{19}*8[/tex] = 16m.

Answer:

∠ 2 = 60°

Step-by-step explanation:

the exterior angle of a triangle is equal to the sum of the 2 remote interior angles.

123° is an exterior angle of the triangle , then

∠ 2 + 63° = 123° ( subtract 63° from both sides )

∠ 2 = 60°

Answer:

60

Step-by-step explanation:

The sum of interior angles in a triangle is equal to 180° so we can write the following equation to find the value of missing angle:

∠2 + 63 + 57 = 180 add like terms

∠2 + 120 = 180 subtract 120 from both sides

∠2 = 60

Answer: EF = 29 units and KM = 22 units

Step-by-step explanation: For the first one, we just add EF and FG, x+14 and 14, and make it equal to EG, 2x+13. We then get x+28 = 2x+13, x = 15. EF = x + 14 and then sub in 15 for x to get 29.

For KM, same deal as the first one. KL and LM, 6 and 2x, equals to KM, 3x-2. 2x+6 = 3x - 2. x = 8. KM = 3x - 2. sub in 8 for x and then we get 22.

Answer:

Step-by-step explanation: its 32

Answer:

Step-by-step explanation:

A + B + C = 180

A = 47

B = 62

C = ???

We don't know what "C" is??

So..

A + B + C = 180

C = 180 - A - B

C = 180 - 47 - 62

Subtract those numbers and you should get 71

Soo..

C = 71

we can also add up

47 + 62 + 71 = 180

The pedestrian route that runs diagonally across the park is 5√10 miles.

It states that in a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides.

We have,

A rectangle:

Length = 15 miles

Wide = 5 miles

Diagonal length can be considered as the hypotenuse.

Applying the Pythagorean theorem.

Diagonal side² = length² + wide²

Diagonal side² = 15² + 5²

Diagonal side² = 225 + 25 = 250

Diagonal side = √250 = 5√10 miles.

Thus the pedestrian route that runs diagonally across the park is 5√10 miles.

The length of the segment BC is equal to 5√3 π / 3.

Herein we find the a geometric system formed by a circle and an inscribed  right triangle formed by two right triangles. By a quick inspection we find the following measures:

AD = 10π, m ∠ BCD = 60°, m ∠ BDC = 30°, m ∠ BDA = 60°, m ∠ BAD = 30°

Then, by 30-60-90 right triangle theorem we find that:

DB = (1 / 2) · AD

DB = (1 / 2) · 10π

DB = 5π

DB = √3 · BC

BC = (√3 / 3) · DB

BC = 5√3 π / 3

The simple interest rate will be 19.2% per year.

We need to find the simple interest which is I = P * R * T

where,

I is the interest,

P is the principal,

R is the interest rate and

T is the time period.

Here, I = the amount you payed - the amount that you owed

= $1800 - $1300 = $500

Now, I = 500

T = 2 years

P = 1300

According to the formula,

500 = 1300 * R * 2

⇒ 500 = 2600* R

∴R = 500/2600 = 0.1923

Multiplying it by 100, we get 19.23%.

Rounding off 1 decimal place, we get 19.2%.

[tex]\bold{n\equiv 91a+40b\ mod \ 130}[/tex]

Given that a is the remainder when n is divided by 10. Then, [tex]n\equiv a\ mod 10[/tex]

Also b is the remainder when n is divided by 13 i.e., [tex]n\equiv b\ mod 13[/tex]

Then by Division algorithm, there are integers k and m such that n = a + 10k and n = b + 13m

These two equations are equivalent to

13n = 13a +130k and 10n = 10b + 130m

Adding these two equations, 23n = 13a + 10b + 130(k + m)

⇒ [tex]23n\equiv 13a+10b\ mod\ 130[/tex]

gcd (23,130) = 1

So 23 has an inverse modulo 130.

Therefore, [tex]n\equiv 23^{-1} (13a+10b) \ mod\ 130[/tex]

Applying Euclidean algorithm for 130 and 23,

130 = 23 x 5 + 15

23 = 1 x 15 +8

15 = 1 x 8 +7

8 = 1 x 7 + 1

Therefore, 1 = 8 - 7 = 8 - (15 -8 ) = 2 x 8 - 15 = 2( 23 - 15 ) - 15

                    = 2 x 23 -3 x 15 = 2(23) -3(130-5x23) =17(23) -3(130)

So inverse of 23 = 17

So, [tex]n\equiv 17 (13a+10b) \ mod\ 130\equiv 221a +170b \ mod \ 130 \equiv \bold{91a+40b \ mod\ 130}[/tex]
