How do I find these angle measures?

Mathematics

The measure of angle 1 is 75 degrees because it is a corresponding angle with the one given of 75 degrees
the measure of angle 2 is 105 degrees because it forms a supplementary angle with the one next to it that is 75 degrees. (this means they add up to 180 degrees.

M∡1 = 75° because when parallel lines are cut by a transversal, corresponding angles are congruent

m∡2 = 180° - 75° = 105° because when adjacent angles form a straight angle (linear pair) they are supplementary

Point AA is located at (5,-6)(5,−6) on the coordinate plane. Point AA is reflected over the xx-axis to create point A'A ′ . What
Free_Kalibri [48]

Answer: (5, 6)

Step-by-step explanation:

   The trick to reflect points over the x -axis is (x, y) to (x, -y). In other words, the x value will stay the same and we will change the sign of the y value.

(5, -6) -> (5, 6)

      The ordered pair to describe A'A' should be (5, 6).

Determine whether set of values represents an inverse variation. If yes, identify the constant of variation and write an inverse
Natasha_Volkova [10]

SOLUTION

If the table represents an inverse variation, it means that y is inversely proportional to x, written as

\begin{gathered} y\propto\frac{1}{x} \\ \propto is\text{ a sign of proportionality } \end{gathered}

Removing the proportionality sign and introducing a constant k, we have

\begin{gathered} y=k\times\frac{1}{x} \\ y=\frac{k}{x} \end{gathered}

In the first column, we have x = -4 and y = 3.5. Substituting these values for x and y, we have

\begin{gathered} y=\frac{k}{x} \\ 3.5=\frac{k}{-4} \\ k=3.5\times-4 \\ k=-14 \end{gathered}

So, if it's an inverse variation, the relationship would be

y=\frac{-14}{x}

In the second column, x = -2 and y = 7.

Now lets substitute the value of x for -2. If we get y to be 7, then the relationship is an inverse variation

We have

\begin{gathered} y=\frac{-14}{x} \\ y=\frac{-14}{-2} \\ y=7 \end{gathered}

Since we got y = 7, the relationship is therefore an inverse variation.

The constant k = -14

The equation for the inverse variation is

y=\frac{-14}{x}

B) (x + 4) 1999 = 1<br> Find x
gulaghasi [49]

Answer:

Step-by-step explanation:

(X+4)1999=1

Open the bracket by multiplying 1999 by the values in the bracket

1999x + 7996 = 1

Collect like terms

1999x = 1-7996

1999x = -7995

Divide both sides by 1999

X = -3.99

Which statement shows the associative property of addition?
AleksAgata [21]
The associative property of addition is shown in equations where the order in which the evaluation is made does not change the result, providing the numbers remain in the same order.  Option B demonstrates this.
