What are the measures of the angles in the triangle? A 60; 60; 60 B 78; 51; 51 (6x + 10º) C 34; 112; 112 D 112; 34; 34 (x + 179) (4x - 349) OA​

Answers

Answer:

D

Step-by-step explanation:

x+17 = 4x-34

-3x = -51

x = 17

17+17= 34

The bottom two are equal so 34, 34

A triangle adds up to 180

180- 68 = 112

So the top is 112

After solving the equation for all three angles of a triangle, the angles are 34, 112, and 34. Hence, option C is correct.

What is a triangle?

The basic polygonal shape of a triangle has three sides and three interior angles. It is one of the elementary objects in geometry and is represented as follows. It has three connected vertices. Triangles can be divided into a variety of categories according to their sides and angles.

As per the given angles of a triangle in the question,

Let angle A = 6x + 10  (i)

Angle B = x + 17 and,   (ii)

Angle C = 4x - 34  (iii)

The submission of all angles will be equal to 180°.

(6x + 10) + x + 17 + 4x - 34 = 180

11x = 187

x = 17

Substitute the value of x in equations to find the angle,

A = 6(17) + 10 = 112

B = 17 + 17 = 34

C = 4(17) - 34 = 34.

These are the angles obtained

Find the sine, cosine, and tangent of angle A. (fraction as in simplest form please.)

Answers

Answer:

SinA=3/5

CosA=4/5

TanA=3/4

Step-by-step explanation:

first we have to find what side length bc is using the Pythagorean triple formula a^2+b^2=c^2 or c^2-b^2=a^2

20^2-16^2=144 the square root of 144 is 12 so side length bc=12

so sin is opposite/hypotenuse

the opposite of angle a is 12 and the hypotenuse is 20 so sinA is 12/20 or 3/5

cos is adjacent/hypotenuse

the adjacent of angle a is 16 and the hypotenuse is 20 so cosA is 16/20 or 4/5

tan is the opposite/adjacent

the opposite of angle a is 12 and the adjacent is 16 so tanA is 12/16 or 3/4

I just need an explanation for both of these! Help would be greatly appreciated, thanks. :))

Answer:

1. Well, to cross multiply them you multiply the numerator in the first fraction times the denominator in the second fraction, then you write that number down. ... The reason we cross multiply fractions is to compare them. Cross multiplying fractions tells us if two fractions are equal or which one is greater.

2. Cross multiplying fractions to find a missing numerator or denominator for equivalent fractions works because it is a shortcut for rearranging to isolate the variable.

If the points (2, 4), (5, k), and (8, 20) are on the same line, what is the value of k?

Answers

Answer:

k = 12

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (2, 4) and (x₂, y₂ ) = (8, 20)

m = [tex]\frac{20-4}{8-2}[/tex] = [tex]\frac{16}{6}[/tex] = [tex]\frac{8}{3}[/tex]

Repeat using (5, k) as one of the points and equate to [tex]\frac{8}{3}[/tex]

(x₁, y₁ ) = (2, 4) and (x₂, y₂ ) = (5, k) , then

m = [tex]\frac{k-4}{5-2}[/tex] = [tex]\frac{k-4}{3}[/tex] = [tex]\frac{8}{3}[/tex] ( cross- multiply )

3(k - 4) = 24 ( divide both sides by 3 )

k - 4 = 8 ( add 4 to both sides )

k = 12

Write a polynomial function f of least degree that has rational coefficients, a leading coefficient of 2, and the given zeros. -4,0,2,4

Answers

Answer:

A least degree polynomial, having rational coefficients and a leading coefficient of 2, with,-4, 0, 2, and 4 as the zeros of the polynomial is;

f(x) = 2·x⁴ - 4·x³ - 32·x² + 64·x

Step-by-step explanation:

The given parameters of the polynomial are;

The leading coefficient of the polynomial = 2

The zeros of the polynomial = -4, 0, 2, 4

We note that zeros of -4, and 4 gives a factor of the form, (x² - 4²)

For a zero of the polynomial equal to 0, one of the factors of the polynomial is equal to 'x'

To have a leading coefficient of 2, we can add '2' as a factor of the polynomial

Therefore, we can have the factors of the polynomial as follows;

(x² - 4²)·2·x×(x - 2) = 0

From the above equation, using a graphing calculator, we get the following possible polynomial;

(x² - 4²)·2·x×(x - 2) = 2·x⁴ - 4·x³ - 32·x² + 64·x = 0

Therefore, a polynomial, function of least degree that has rational coefficients, a leading coefficient of 2,and the zeros, -4, 0, 2, and 4 is  f(x) = 2·x⁴ - 4·x³ - 32·x² + 64·x.

Answer:  (2,3)

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

Explanation:

The intersection point of the two lines is where the solution point is located.

The x coordinate of that intersection point is a bit smaller than x = 2, but when rounded to the nearest whole number, we would get to x = 2.

At the same time, the y coordinate of the intersection point is a bit above y = 3, which rounds to this value when rounding to the nearest whole number.

So that's how we get to (2,3)

Solve each of the following system of equations by substitution!!!

x-5y=-49
y=-2x+1

Answers

Answer:

x = -4, y = 9

or

(-4, 9)

Step-by-step explanation:

x - 5y = -49

y = -2x + 1

substitute y for -2x + 1

x - 5(-2x + 1) = -49

x + 10x - 5 = - 49

add 5 to both sides

x + 10x - 5 + 5 = - 49 + 5

x + 10x = -44

11x = -44

divide both sides by 11

11x/11 = -44/11

x = -4

substitute x for -4 in any of the original equations

y = -2x + 1

y = -2 * -4 + 1

y = 8 + 1

y = 9

Answer:

x = -4, y = 9 or (-4,9)
