Find the missing values of the variables. The diagram is not to scale. (Image attached below)thank you ! :)
aniked [119]

Answer:

\begin{gathered} x=\text{ 99}\degree \\ y\text{ = 64}\degree \end{gathered}

Explanation:

Here, we want to get the value of x and y

From the given image, the angle y and 116 lie on a straight line

The sum of the angles on a straight line is 180 degrees

Thus:

\begin{gathered} 116\text{ + y = 180} \\ y\text{ =180-116} \\ y\text{ = 64}\degree \end{gathered}

The sum of the internal angles of a polygon can be calculated by the formula:

180(n-2)

where n is the number of sides the polygon has

In the case of the given question, n is 4

Substituting the value of n, we have it that:

180(4-2)\text{ = 360 degrees}

To get the value of x:

\begin{gathered} x\text{ + y + 125 + 72 = 360} \\ But\text{ from above , y = 64}\degree \\ Substituting\text{ this:} \\ x\text{ + 64 + 125 + 72 = 360} \\ x\text{ = 360-125-64-72} \\ x\text{ = 99 } \end{gathered}

Estimate 843/84 by first rounding each number so that it has only 1 nonzero digit
mezya [45]

Answer:

10 is your answer.

Step-by-step explanation:

Both 843 and 84 will be turned to 800/80 because 4 is below 5 so it will be turned into a zero and the 8 left an 8.

800/80=10 is your answer.

Umnica [9.8K]

Answer:

Julio debe $ 41225 al banco por concepto del préstamo para invertir en su casa.

Step-by-step explanation:

Dada la falta de información, asumimos que el préstamo fue realizado sin tasa de interés, de modo que la deuda solo sea el monto inicial menos las cuotas pagadas por quien recibe el préstamo, la cantidad de dinero que adeuda al banco es:

x = \$\,100000 - \$\,32950 - \$\,25825

x = \$ \,41225

Julio debe $ 41225 al banco por concepto del préstamo para invertir en su casa.

If the signs of the coordinates of collinear points P(-6,-2), Q(-5,2), and R (-4,6) reversed, are the 3 new points still colline
Strike441 [17]

If all the points have the signs reversed, therefore this means that the whole line is reflected about an axis. Since all are reflected therefore this further means that the new points are still collinear.

 

We can prove this by plotting the points:

P’(6,2), Q(5,-2), R(4,-6)

<span>From the graph, they are in 1 line hence collinear.</span>
