(b) 17.9m

Step-by-step explanation:

According to the attachment

⠀

let AB be the ladder

BC be the distance between the ladder and wall

⠀

(a) We have to find ∠A by trigonometry formula

[tex] \sf \sin A = \frac{perpendicular}{hypotenuse} [/tex]

Here angle A is facing BC so it is perpendicular

and AB is the longest side so it is hypotenuse

[tex] \sf \implies \sin A = \frac{BC}{AB} \\ \\ \\ \sf \implies \sin A = \frac{9}{20} \\ \\ \\ \sf \implies \sin A = 0.45 \\ \\ \\ \sf \implies \sin A = \sin27{ \degree} \\ \\ \\ \sf \purple {A = 27{ \degree}}[/tex]

(b)

AC is the distance from the upper end of the ladder to ground

we will find it by Pythagoras theorem

[tex] \sf {hypotenuse}^{2} = {perpendicular}^{2} + {base}^{2} \\ \\ \\ \sf \implies {AB}^{2} = {BC}^{2} + {AC}^{2} \\ \\ \\ \sf \implies {20}^{2} = {9}^{2} + {AC}^{2} \\ \\ \\ \sf \implies 400 = 81 + {AC}^{2} \\ \\ \\ \sf \implies 400 - 81 = {AC}^{2} \\ \\ \\ \sf \implies 319 = {AC}^{2} \\ \\ \\ \sf \implies \sqrt{319} = AC \\ \\ \\ \sf \blue{\implies 17.86 = AC}[/tex]

To solve this problem, we have to understand that the parallel lines cut will form two alternate angles which are equal to each other. The value of x is equal to -8/5

In the given question, we have two alternate angles fixed at opposite end to each other.

Data;

Since we've established that alternate angles are equal to each other, we can proceed to equate the two angles and solve for x

[tex]8x -1 = 3x - 9\\8x - 3x = - 9 + 1\\5x = - 8\\x =-\frac{-8}{5}[/tex]

The value of x is equal to -8/5

Answer:

84 degrees

Step-by-step explanation:

180-96=84

The correct value in this function is f(21) = 157

This question is related to substitution of values. To solve it, just: change x by the indicated value and thus calculate normally.

– The given function being f(x) = 8x - 11, replace X by 21:

f(x) = 8x - 11

f(21) = 8 . 21 - 11

– Finally, just calculate the expression now, like this, multiplying and subtracting the numbers:

f(21) = 8 . 21 - 11

f(21) = 168 - 11

f(21) = 157

Therefore, the correct value of this function will be f(21) = 157

The best approximation of the factor by which the population increases over a ten years period will be 6.19.

The exponent denotes that the base will rise to a specific level of strength. The base is X, and the power is n.

A certain buffalo population increases by a factor of 1.2 each year.

Then the best approximation of the factor by which the population increases over a ten years period will be

→ 1.2¹⁰

→ 6.1917

→ 6.19

Answer:

Step-by-step explanation:

The relation that helps you write an equation for x is, "the sum of angles in a triangle is 180°."

__

  (4x -4)° +x° +(6x -3)° = 180° . . . . . sum of angles in this triangle

  11x -7 = 180 . . . . . . . divide by °, collect terms

  11x = 187 . . . . . . . . add 7

  x = 17 . . . . . . . . . divide by 11

  m∠J = (6x -3)° = (6(17) -3)° = 99°

  m∠K = (4x -4)° = (4(17) -4)° = 64°

  m∠L = x° = 17°

Answer:

76 unit^2

Step-by-step explanation:

Total area: (0.5  * base * height) +( length * breadth ) + (0.5 * base * height)

= (0.5 * 8 * 2) + ( 7*8) +( 0.5 * 8 * 3) = 8 + 56 + 12 = 76

Answer:22

Step-by-step explanation:

23 plus 26 plus 25 plus 24 plus 23 plus 24 plus 6 plus 24 plus 23= 198 so count how many numbers there are we had to add so its 198 divided by 9 gives you the answer  22

The answer is the orange one because pie * radius^2 leads to the area of the circl.e

Answer:

true

Step-by-step explanation:

Examples :

180 = 5 × 2² × 3²

Then

The number 180 has perfect square factors which are 2 and 3

Then

The number √180 can be simplified because:

[tex]\sqrt{180} =\sqrt{5\times 2^{2}\times 3^{2}}[/tex]

        [tex]=\sqrt{5\times \left( 2\times 3\right)^{2} }[/tex]

        [tex]=\sqrt{5\times \left( 6\right)^{2} }[/tex]

        [tex]=\sqrt{5} \times \sqrt{6^{2}}[/tex]

        [tex]=6\sqrt{5}[/tex]

On the other hand :

10 = 5 × 2

Then

The number 10 has no perfect square factors

Then

The number √10 cannot be simplified because:

[tex]\sqrt{10} =\sqrt{5\times 2} =\sqrt{5} \times \sqrt{2}[/tex]

[tex]\text{and} \ \sqrt{5} \times \sqrt{2} \ \text{is not a simplified expression of} \ \sqrt{10} \ \\\text{,in fact it is more complicated than} \ \sqrt{10}[/tex]

Step-by-step explanation:

a=edge

Unit Conversion:

a=30mm/1000m

a=0.03m

Solution

V= a³= 0.03³

a³=0.03x0.03x0.03 ≈ 2.7×10^-5m³

Answer:

Arc AB = 55°

Angle AOB = 55° ( Centre angle is equal to respective arc )

Arc CD = 25°

Angle COD = 25° ( Centre angle is equal to respective arc )

Angle AOB + Angle BOC + Angle COD = 180° ( AD is the diameter)

55° + Angle BOC + 25° = 180°

Angle BOC + 80° = 180°

Angle BOC = 100°

Given 3x and 5x --------------- (i)

(3x+10)/(5x+10) = 5/7

21x + 70 = 25x + 50

4x = 20

x = 5

Answer:

The answer is one solution because the graphs are together in one specific point.

Answer:

Two solutions

Step-by-step explanation:

Answer:

d)The midline is y=1.5

Step-by-step explanation:

Because you can see in the graph that the midline is 1. So only c is no correct.

The amplitude is measured between the midline and the pik(highest or lowest value) of the function. This case is 2. True

The period is the distance between “equivalent” points. pi in this case. True.

The phase shift occur when the function is shifted on the x-axis. There is no phase shift. True.
