Step-by-step explanation:

x= 180 - 75 - 43

Answer:

75.36

Step-by-step explanation:

bc it sinple math if you think about it

Given:

[tex]\alpha, \beta, \gamma[/tex] are three interior angles of any triangle.

To prove:

[tex]\cos (\alpha+\beta+\gamma)=-1[/tex]

Solution:

Angle sum property of a triangle: According to this theorem the sum of all three interior angle of a triangle is always 180 degrees.

It is given that, [tex]\alpha, \beta, \gamma[/tex] are three interior angles of any triangle.

By using the angle sum property of triangles, we get

[tex]\alpha+\beta+\gamma =180^\circ[/tex]              ...(i)

We need to prove,

[tex]\cos (\alpha+\beta+\gamma)=-1[/tex]

Taking LHS, we get

[tex]LHS=\cos (\alpha+\beta+\gamma)[/tex]

[tex]LHS=\cos (180^\circ)[/tex]                [Using (i)]

[tex]LHS=-1[/tex]

[tex]LHS=RHS[/tex]

Hence proved.

Answer:

y=15

x=43

(any variable can be used, I used x and y to make it easier to show)

Step-by-step explanation:

x+y=58

x-y=28

get x by its self

x=58-y

then subsitute into the other equation

(58-y)-y=28

58-2y=28

-2y=-30

y=15

sub. again

x+15=58

x=43

Answer:

5√(7)m  or 13.23m

Step-by-step explanation:

use pythagorean theorem

a²+b²=c²

c=20

b=15

a²+225=400

a²=175

√(175) = 5√(7) = 13.23

The height of the kite is 13.23 meters.

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.

Given:

A boy is flying a kite.

The length of the string is 20 meters and the horizontal distance between the boy and the kite is 15 meters.

Assuming there is no slack in the string,

then the height of the kite is,

= √(20)² - (15)²

= 13.23 feet.

Therefore, the height is 13.23 meters.

Answer:

73

Explanation

To find the average we need to find the mean. So you have

87,93,96, and 89. Add it up and you get 365. Next you have to divide it by how many numbers there are, so 365 divided by 5 and you get 73.

(I divided 365 by 5 because we are looking for the score she needs on the 5th quiz too.)

Answer:

horizontal asymptote at y = 2, vertical asymptote at x = 1

Step-by-step explanation:

We are given the following function:

[tex]f(x) = \frac{2x}{x - 1}[/tex]

Horizontal asymptote:

The horizontal asymptote of a function is the limit of the function as the input, in this case x, goes to infinity. When we want to find the limit of x going to infinity of a fraction we consider the term with the largest exponent on both the numeration and the denominator. So

[tex]\lim_{x \rightarrow \infty} \frac{2x}{x - 1} = \lim_{x \rightarrow \infty} \frac{2x}{x} = \lim_{x \rightarrow \infty} 2 = 2[/tex]

So there is a horizontal asymptote at y = 2

Vertical asymptote:

Vertical asymptotes happens at points outside the function domain.

In this question, we have a fraction, in which the denominator cannot be 0. So

[tex]x - 1 = 0 \rightarrow x = 1[/tex]

Thus, there is a vertical asymptote at x = 1.

The correct option is:

horizontal asymptote at y = 2, vertical asymptote at x = 1

A pentagon's largest internal angle is 150 degrees.

The geometric shape known as a pentagon has five sides and five angles. Penta here means five, and gon means angle. One of the different kinds of polygons is the pentagon. A regular pentagon's internal angles add up to 540 degrees.

Given, The measures of the interior angles of a pentagon are 2x + 15, 3x, 3x + 5, 4x + 10, and 5x. Since the sum of all the interior angles of the pentagon is 540 degrees. Hence

2x + 15 + 3x + 3x + 5 + 4x + 10 + 5x = 540

17x  + 30 = 540

17x  = 510

x = 30

All five angles of the pentagon are 75, 90, 95, 130, and 150.

Therefore, the biggest interior angle of a pentagon is 150 degrees.

Answer:

In standard form, the relation is [tex]y = 5x^2 + 100x + 507[/tex]

The y-intercept is y = 507.

Step-by-step explanation:

Quadratic equation:

In standard form, it is written as:

[tex]y = ax^2 + bx + c[/tex]

The y-intercept is c.

a) y = 5(x+10)^2 +7

We open the binomial to write in standard form. So

[tex]y = 5(x + 10)^2 + 7[/tex]

[tex]y = 5(x^2 + 20x + 100) + 7[/tex]

[tex]y = 5x^2 + 100x + 500 + 7[/tex]

[tex]y = 5x^2 + 100x + 507[/tex]

In standard form, the relation is [tex]y = 5x^2 + 100x + 507[/tex]

The independent term, c, is 507, so the y-intercept is y = 507.

Answer:

Mean weight = 19 pounds

Step-by-step explanation:

From the question given above, the following data were obtained:

17, 11, 21, 24, 22

Number of data (n) = 5

Mean weight =?

The mean of a set of data is the value obtained by adding all the data together and dividing the result obtained by the total number of data. Thus, the mean can be obtained as follow:

Summation of data = 17+ 11 + 21 + 24 + 22

= 95

Number of data = 5

Mean = Summation of data / Number of data

Mean = 95 / 5

Mean weight = 19 pounds

Therefore, the mean weight of the data is 19 pounds

Perimeter of JKL = 22.55 unit (Approx.)

Step-by-step explanation:

Given:

Coordinate of J = (2,3)

Coordinate of K = (10,4)

Coordinate of L = (6,10)

Find:

Perimeter of JKL

Computation:

Distance = √(x1 - x2)² + (y1 - y2)²

Distance between JK = √(2 - 10)² + (3 - 4)²

Distance between JK = √64 + 1

Distance between JK = √65

Distance between JK = 8.06 unit

Distance between KL = √(10 - 6)² + (4 - 10)²

Distance between KL = √16 + 36

Distance between KL = √52

Distance between KL = 7.21 unit

Distance between LJ = √(6 - 2)² + (10 - 3)²

Distance between LJ = √4 + 49

Distance between LJ = √53

Distance between LJ = 7.28 unit

Perimeter of JKL = Distance between JK + Distance between KL + Distance between LJ

Perimeter of JKL = 8.06 + 7.21 + 7.28

Perimeter of JKL = 22.55 unit (Approx.)
