Answer 1

Answer:

b= 64 m

Step-by-step explanation:

[tex]b^{2}[/tex] + [tex]48^{2}[/tex] = [tex]80^{2}[/tex]

[tex]b^{2}[/tex] = [tex]80^{2}[/tex] - [tex]48^{2}[/tex]

[tex]b[/tex] = [tex]\sqrt{80^{2}-48^{2} }[/tex]

Let the measure of the altitude of the given triangle be h units.

By geometric mean theorem:

[tex]h = \sqrt{23 \times x} \\ \\ h = \sqrt{23x} \\ \\ now \: by \: pythagors \: theorem \\ \\ {(x + 11)}^{2} = {h}^{2} + {x}^{2} \\ \\ \cancel{{x}^{2}} + 22x + 121 = {( \sqrt{23x} )}^{2} + \cancel{{x}^{2}} \\ \\ 22x + 121 = 23x \\ \\ 22x - 23x = - 121 \\ \\ - x = - 121 \\ \\ x = 121[/tex]

How to find the slope for (2,2) and (-1,2)

Answers

Answer:

Slope = 0

slope is the same as gradient, so you will use the formula

M = y2 - y1 / x2 - x1         in this case (2,2)          and (-1.2)

    the first 2,is x1.then the other 2 in the first coordinate is y1 , for the last coordinate -1 is x2 and 2 is y2, use the formula I gave you , you will see that the answer is 0

The value of tan60° is ______ . * 1 point 1/√3 0 1 √3

Answers

Answer:

Therefore, the exact value of Tan 60 degrees is √3. We can also derive the values of tan 0°, 30°, 45°, 90°, 180°, 270° and 360° in the same way

The value of tan 60° is √3, approximately 1.732.

To calculate the value of tan 60°, we need to use the trigonometric function tangent. Tan 60° represents the ratio of the length of the side opposite the angle to the length of the adjacent side in a right triangle with a 60° angle.

In a 30°-60°-90° right triangle, the length of the opposite side opposite the 60° angle is equal to the square root of 3 times the length of the adjacent side.

The length of the opposite side is √3, and the length of the adjacent side is 1.

Using these values, we can calculate the value of tan 60°:

tan 60° = (opposite side) / (adjacent side) = (√3) / 1 = √3.

Therefore, the value of tan 60° is √3, approximately 1.732.

Please help me solve this

Answers

Answer:

1st pic:

x = 61

left angle = 125 degrees

right angle = 55 degrees

2nd pic:

n = 14

left angle = 78 degrees

right angle = 102 degrees

Step-by-step explanation:

1st pic:

use the following equation ⇒ 2x + 3 + x - 6 = 180

combine like terms ⇒ 3x - 3 = 180

add 6 on both sides ⇒ 3x - 3 + 3 = 180 + 3 ⇒ 3x = 183

divide both sides by 3 ⇒ [tex]\frac{3x}{3} = \frac{183}{3}[/tex]

x = 61

solve the angles by subtituting 61 for x

left angle = 2x + 3 ⇒ 2 x 61 + 3 ⇒ 125 degrees

right angle = x - 6 ⇒ 61 - 6 ⇒ 55 degrees

2nd pic:

use the following equation ⇒ 4n + 22 + 8n - 10 = 180

combine like terms ⇒ 12n + 12= 180

subtract 12 on both sides ⇒ 12n + 12 - 12 = 180 - 12 ⇒ 12n = 168

divide both sides by 12 ⇒ [tex]\frac{12n}{12} = \frac{168}{12}[/tex]

n = 14

you can find the angles by substituting 14 for n:

left angle = 4n + 22 ⇒ 4 x 14 + 22 =78 degrees

right angle: 8n - 10 ⇒ 8 x 14 - 10 = 102 degrees

A quadratic function is represented by the graph. (graph below.) (do a-d.)

(a) What is the equation of the axis of symmetry of the function?
(b) What are the coordinates of the vertex of the function?
(c) What are the coordinates of the x-intercepts of the function?
(d) What are the coordinates of the y-intercept of the function?

Answers

Answer:

The axis of symmetry is x=1

The vertex is (1,-9)

The x-intercepts are (4,0) and (-2,0)

The y-intercept is (0,-8)

Step-by-step explanation:

axis of symmetry is the line where the vertex is, so in the quadratic of x^2, the axis of symmetry would be zero because half of the equation is on one side and the other half on the other side

The vertex is the lowest point on the quadratic, on the y values

the x-intercepts are the places the graph intercepts the x-axis.

The y-intercepts are the places the graph intercepts the y-axis
