What Is The Perimeter Of The Triangle?218X

Answers

Answer 1

Answer:

Step-by-step explanation:

P=a+b+c

Right scalene triangle.

Sides: a = 21   b = 8   c = 22.472

Area: T = 84

Perimeter: p = 51.472

Semiperimeter: s = 25.736

Angle ∠ A = α = 69.146° = 69°8'44″ = 1.207 rad

Angle ∠ B = β = 20.854° = 20°51'16″ = 0.364 rad

Angle ∠ C = γ = 90° = 1.571 rad

Height: ha = 8

Height: hb = 21

Height: hc = 7.476

Median: ma = 13.2

Median: mb = 21.378

Median: mc = 11.236

Inradius: r = 3.264

Circumradius: R = 11.236

Vertex coordinates: A[22.472; 0] B[0; 0] C[19.624; 7.476]

Centroid: CG[14.032; 2.492]

Coordinates of the circumscribed circle: U[11.236; -0]

Coordinates of the inscribed circle: I[17.736; 3.264]

Exterior (or external, outer) angles of the triangle:

∠ A' = α' = 110.854° = 110°51'16″ = 1.207 rad

∠ B' = β' = 159.146° = 159°8'44″ = 0.364 rad

∠ C' = γ' = 90° = 1.571 rad

Opposite exterior angles are congruent

Hence, x = 106

Do you think two students who made no computation errors would get different values for this numerical expression> explain (4x35)+(36x8

Answers

Answer:

Yes, they would get different values

Step-by-step explanation:

Given

[tex](4 * 35) + (36 * 8)[/tex]

Required

Would there be different value for the expression?

From the question, we understand that both students made no computational errors. This doesn't mean that the students cannot make other errors.

For instance, the expression can be solved (wrongly) in the following ways;

[tex](4 * 35) + (36 * 8) \to 4 * 35 + 36 * 8 \to 140 + 36 * 8 \to 176 * 8 = 1408[/tex]

[tex](4 * 35) + (36 * 8) \to 4 * 35 + 36 * 8 \to 4 * 71 * 8 \to = 2272[/tex]

While the correct solution is:

[tex](4 * 35) + (36 * 8) \to 140 + 288 =428[/tex]

Hence, it is possible for two students to get different values

The length of one leg of a right triangle is 20.3 centimeters. The length of the hypotenuse is
30.7 centimeters. Which is closest to the length of the other leg?

Answers

Answer:  Approximately 23.0 cm

=====================================================

Work Shown:

a = 20.3

b = unknown

c = 30.7

Apply the pythagorean theorem to find b

a^2 + b^2 = c^2

(20.3)^2 + b^2 = (30.7)^2

412.09 + b^2 = 942.49

b^2 = 942.49-412.09

b^2 = 530.4

b = sqrt(530.4)

b = 23.0304146727757  value is approximate

b = 23.0

I rounded to one decimal place because the other values (20.3 and 30.7) were to one decimal place.

B)
The coordinate pair (-1, 4) represents a point on the graph and a solution

The coordinate pair (-2, 1) represents a point on the graph and a solution

D)
The coordinate pair (-3, 2) represents a point on the graph and a solution
to the equation
E)
The coordinate pair (-4,-8) represents a point on the graph and a solution
to the equation.

Answers

b and e if you plug it in desmos it gives you direct coordinates

The correct statements are:

- The coordinate pair (-2, 1) represents a point on the graph and a solution to the equation.

-The coordinate pair (-4, -8) represents a point on the graph and a solution to the equation.

Options C and E are the correct answer.

We have,

The equation y = 4x + 8 represents a linear relationship between x and y.

To determine which statements are correct, we need to substitute the x-coordinate of each given coordinate pair into the equation and see if it satisfies the equation.

A) The coordinate pair (0, 10)

Substituting x = 0 into the equation: y = 4(0) + 8 = 8

So, (0, 10) does not satisfy the equation.

Statement A is incorrect.

B) The coordinate pair (-1, 4)

Substituting x = -1 into the equation: y = 4(-1) + 8 = 4 + 8 = 12

So, (−1, 4) does not satisfy the equation.

Statement B is incorrect.

C) The coordinate pair (-2, 1)

Substituting x = -2 into the equation: y = 4(-2) + 8 = -8 + 8 = 0

So, (−2, 1) does satisfy the equation.

Statement C is correct.

D) The coordinate pair (-3, 2)

Substituting x = -3 into the equation: y = 4(-3) + 8 = -12 + 8 = -4

So, (−3, 2) does not satisfy the equation.

Statement D is incorrect.

E) The coordinate pair (-4, -8)

Substituting x = -4 into the equation: y = 4(-4) + 8 = -16 + 8 = -8

So, (−4, -8) does satisfy the equation.

Statement E is correct.

Therefore,

The correct statements are:

- The coordinate pair (-2, 1) represents a point on the graph and a solution to the equation.

-The coordinate pair (-4, -8) represents a point on the graph and a solution to the equation.

G = (-5,-5)

Step-by-step explanation:

d = sqrt (x^2 - x^1)^2 + (y^2 - y^1)^2

Let's use the coordinate pairs: (6,4) and (6,-5).

Input.

d = sqrt (6 - 6)^2 + (-5 - 4)^2

Solve.

d = sqrt 0 + (-9)^2

d = sqrt 0 + 81

d = sqrt 81

d = 9

Count 9 places back from (6, -5) , then you will arrive at (-5,-5).

Thus, the fourth vertex of the rectangle "EFGH" is (-5,-5) for G.

Complete question

Mr porter had eight parties at her house last year the number of guests at each party is shown below 15,19,9,27,21,21,10,14. What is the median numbers of those parties

The median value is the value at the middle after rearrangement

On rearranging in ascending order

9, 10, 14, (15, 19), 21, 21, 27

Since there are two values in the middle, we will take the average of the numbers

Median = 15+19/2

Median = 34/2

Median = 17

Hence the median value is 17

10. RECREATION In a game of kickball, Rickie has to kick the
ball through a semicircular goal to score. If m XZ = 58 and
the m XY = 122, at what angle must Rickie kick the ball to
score? Explain.

Answers

Answer:

The angle Rick must kick the ball to score is an angle between the lines BX and BZY which is less than or equal to 32°

Step-by-step explanation:

The given measures of the of the angle formed by the tangent to the given circle at X and the secant passing through the circle at Z and Y are;

[tex]m\widehat{XZ} = 58^{\circ}[/tex]

[tex]m\widehat{XY} = 122^{\circ}[/tex]

The direction Rick must kick the ball to score is therefore, between the lines BX and BXY

The angle between the lines BX and BXY = ∠XBZ = ∠XBY

The goal is an angle between [tex]m\widehat{XY}[/tex]

Let 'θ' represent the angle Rick must kick the ball to score

Therefore the angle Rick must kick the ball to score is an angle less than or equal to ∠XBZ = ∠XBY

By the Angle Outside the Circle Theorem, we have;

The angle formed outside the circle = (1/2) × The difference of the arcs intercepted by the tangent and the secant

[tex]\therefore \angle XBZ = \dfrac{1}{2} \times \left (m\widehat{XY} -m\widehat{XZ} \right)[/tex]

We get;

∠XBZ = (1/2) × (122° - 58°) = 32°

The angle Rick must kick the ball to score, θ = ∠XBZ ≤ 32°
