Answer:

x=20,y=34

Step-by-step explanation:

x+14=2x-6 (vertically opposite angles)

x-2x = -6-14

-x = -20

x=20

x+14=y (corresponding angles)

20+14=y

y=34

Answer:

x = 20, y = 34

Step-by-step explanation:

(2x - 6) and (x + 14) are vertical angles and are congruent, then

2x - 6 = x + 14 ( subtract x from both sides )

x - 6 = 14 ( add 6 to both sides )

x = 20

Then

2x - 6 = 2(20) - 6 = 40 - 6 = 34

y and (2x - 6) are alternate angles and are congruent , so

y = 34

Find all the missing elements:

Evgesh-ka [11]

Answer:

a=10.8; c=4.3

Step-by-step explanation:

The sum of all the angles in a triangle is 180 degrees.

Two of the angles are given as 40 deg and 120 deg.

Subtract the measures of both from the sum to get the last angle:

180-40-120=20; ∠C=20°

Using Law of Sines: $\frac{a}{sinA}=\frac{b}{sinB}=\frac{c}{sinC}$

$\frac{a}{sin120}=\frac{8}{sin40}; a=\frac{8*sin120}{sin40}; a=10.77837084$

$\frac{c}{sin20}=\frac{8}{sin40}; a=\frac{8*sin20}{sin40}; c=4.25671109$

Find all rational solutions of the equation x8−4x5+13x3−7x+1=0.

drek231 [11]

Answer:

The rational roots of the equation are:

x= -1.10355

x= 0.148953

x= 0.706883

x= -1

Step-by-step explanation:

We have to find the rational solutions of the algebraic equation:

$x^8-4x^5+13x^3-7x+1=0.$

This equation could also be written as:

$(x+1)(x^7-x^6+x^5-5x^4+5x^3+8x^2-8x+1)=0$

for finding the roots of the equation we have to find the possible values of x.

Clearly the equation has 8 roots as the degree of the equation is 8.

from the graph of the following function we could see that the rational roots of the function are:

x= -1.10355

x= 0.148953

x= 0.706883

x= -1

The rest 4 roots of the equation are the complex roots.

What are the factors of 70, 86,154,238

Strike441 [17]

70 = 1 x 70, 2 x 35, 5 x 14, and 7 x 10. It is usually written as 1,2,5,7,10,14,35,70

86 = 1 x 86 or 2 x 43. It can be written as 1,2,43,86

154 = 1 x 154, 2 x 77, 7 x 22, 11 x 14. Can be written as 1,2,7,11,14,22,77,154

238 = 1 x 238, 2 x 119, 7 x 34, or 14 x 17. Can be written as 1,2,7,14,17,34,119,138
