Answer:

A

Step-by-step explanation:

Draw an angle of 15° like this (∠) on a piece of paper, label this angle J, extend the base of the triangle and label the hypotenous 11cm (JK). Do you get the solution now? If no, here is an explanation.

This problem can be explained with sin law,

[Assume KL = 4cm]

(sin15)/4 = (sinL)/11

L = 45.4° or 135° (3 sig. fig.)

Since we got 2 possible case for the angle L, there are two possible set of triangles. Hope this will help you understand more about the problem, comment below if you still have any questions.

Total surface area is: 21 ft²

Lateral area is: 12π ft²

The total surface area of this cone is 21π square feet.

The total surface area of the cone is given by the following formula;

[tex]\rm Surface \ area=\pi r(r+l)[/tex]

Where h denotes the height of the cone and r is the radius and l is the slant height.

The radius of the cone = 3

The height of the cone = 4

Substitute all the values in the formula

[tex]\rm Surface \ area=\pi r(r+l)\\\\\rm Surface \ area=\pi 3(4+3)\\\\\rm Surface \ area=3\pi \times 7\\\\\rm Surface \ area=21\pi[/tex]

Hence, the total surface area of this cone is 21π square feet.

Answer:

En 2001 el pueblo poseía 45.826 habitantes.

Step-by-step explanation:

Un pueblo tenía 13.578 habitantes en 1970. En 1988 la población se incrementó 1,5 veces con respecto a 1970. Para calcular entonces la población en 1988 debes realizar el siguiente cálculo:

13.578*1,5= 20.367

Por lo que en 1988 el pueblo poseía 20.367 habitantes.

En 2001 se incrementó la población 2,25 veces en relación a 1988. Para calcular entonces la población en 2001 debes realizar el siguiente cálculo:

20.367* 2,25= 45.825,75≅ 45.826

Por lo que en 2001 el pueblo poseía 45.826 habitantes.

Answer:

A = 30°

x = 9·√3

Step-by-step explanation:

Part A

In the drawing, we are given;

The radius of the circle with center at point S = SA = 18

ΔAHA is a right triangle

One of the leg length of ΔASH = 9

The length of the hypotenuse side of ΔASH, AS = 18 The radius of the circle with center at the point 'S'

By Pythagoras's theorem, the length of the (radius) side, AS  = √(SH² + AH²)

∴ AH = √(AS² - SH²)

AH = √(18² - 9²) = √(243) = 9·√3

AH = 9·√3

By circle theorem, SH bisects the line AH extended to the circumference of the circle

SH bisects the line with length AH + x

∴ AH = x

x = AH = 9·√3

x = 9·√3

Part B

By trigonometric ratios, we have;

[tex]sin\angle A = \dfrac{Opposite \ leg \ length}{Hypotenuse \ length}[/tex]

[tex]\therefore sin\angle A = \dfrac{9}{18} = \dfrac{1}{2}[/tex]

∠A = arcsine (1/2) = 30°

Angle A = 30°

Answer:

x = 28

Step-by-step explanation:

ΔARP ≈ ΔCRD

42/x = 57/(10+x)

cross-multiply:

42(10+x) = 57x

420 + 42x = 57x

420 = 15x

28 = x

Answer:x = 8.5

Step-by-step explanation:

1. Combine like terms

62+75+9 = 146

2.Set up equation

146+4x = 180

3. Subtract 146 to each side

146-146 + 4x = 180-146 = 34

4. Divide by 4

4x/4 = 34/4

X= 8.5

Step-by-step explanation:

Answer:

[tex]a_{n}[/tex] = 4n + 3

Step-by-step explanation:

There is a common difference between consecutive terms, that is

11 - 7 = 15 - 11 = 19 - 15 = 4

This indicates the sequence is arithmetic with nth term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 7 and d = 4 , then

[tex]a_{n}[/tex] = 7 + 4(n - 1) = 7 + 4n - 4 = 4n + 3

Answer:

  y = 7/3x +13/3

Step-by-step explanation:

The equation of the given line is in slope-intercept form (y=mx+b), so we can see the slope (m) is -3/7. The slope of the perpendicular line is the opposite reciprocal of this, so is ...

  m = -1/(-3/7) = 7/3

The y-intercept of the perpendicular line can be found from ...

  b = y -mx

  b = -5 -(7/3)(-4) = -15/3 +28/3 = 13/3

Then the slope-intercept equation of the perpendicular line is ...

  y = mx +b

  y = 7/3x +13/3

Additional comment

You can get there a little faster using the point-slope form of the equation of a line. For slope m and point (h, k) that form is ...

  y -k = m(x -h)

For our perpendicular line, the equation is ...

  y +5 = 7/3(x +4)
