Vertical angles are equal, so
.. 3x +8 = 5x -20
.. 28 = 2x . . . . . . . . add 20-3x
.. 14 = x . . . . . . . . . . divide by 2

Each of the vertical angles is 3*14 +8 = 50°, so the supplementary one is 130°.
.. 5*14 +4y = 130
.. 4y = 60 . . . . . . . . subtract 70
.. y = 15 . . . . . . . . . . divide by 4

The values of interest are
.. x = 14
.. y = 15

tell whether the angles are adjacent or vertical then find the value of x. can someone help me please i need all the answers
dmitriy555 [2]

Answer:

3. adjacent; 49
4. adjacent; 71

5. verticle; 41

6. adjacent; 14

Step-by-step explanation:

ok basically if the angles are next to each other, then they're adjacent and if they're across from eachother they're verticle.

to find 3:

set both equations equal to each other and solve because verticle angles are equal

to find 4:

add the 2 equations together and set it equal to 180 because adjacent angles add up to equal either a complementary angle or supplementary depending on the problem

-3 raised to the power 0=
son4ous [18]

Given:

The statement is "-3 raised to the power 0".

To find:

The value of the given expression.

Solution:

We know that a raised to the power b can be written as a^b.

Any non zero number raised to the power 0 is always 1. It means,

a^0=1, where a\neq 0.

-3 raised to the power 0 =(-3)^0

                                         =1

Therefore, the value of the given statement is 1.

Use the expressions that represent the length and width of the game board to write an equation that models the area of the figur
Ne4ueva [31]
The picture is incomplete and the width is missing.

I am going to show you how to do it using any width.

The length shown is x + 4 and the width starts with - x.

Assume the width is - x + a.

Then the area of the rectangle with dimensions x + 4 and - x + a is calculated in this way:

1) given: (x + 4) (- x + a)

2) use distribuitive property: (x)(-x) + (x)(a) + (4)(-x) + (4)(a)

= - x^2 +ax -4x + 4a

3) Combine like terms: - x^2 + (a -4)x + 4a

If the polynomial missing were - x + 7, the answer would be:

- x^2 + (7 -4)x + 4(7) = - x^2 + 3x + 28

With this you are able to get the answer using the real values.
