Answer:

Step-by-step explanation:

So you want to add 7x degrees and (x-4) degrees. And it will be 8x - 4 = 180 degrees because it's 180 degrees in a straight line. And you want to + the 180 by 4 because there is -4 on the other side. so it will be 8x = 184 and you just divide 184 by 8 and it will be 23 easy. if you want to my help again you can text me on instargram jason_lee093

Find the values of the variables in the parallelogram. The diagram is not drawn to scale. (Image is attached below)thank you in

irina1246 [14]

For this problem, we are given a parallelogram with a diagonal drawn, inside it there are markings for a few angles. We need to determine the unknown angles.

Opposite sides of a parallelogram are parallel, this means we can treat the diagonal as a transversal line that crosses two parallel lines. Since this is the case, the angles 33º and xº are alternate interior angles and have the same length:

$x=33º$

The opposite angles in a parallelogram are congruent, therefore:

$z=109º$

The sum of internal angles is 360º, therefore we have:

$\begin{gathered} 2\cdot109+2\cdot(x+y)=360\\ \\ 218+66+2y=360\\ \\ 284+2y=360\\ \\ 2y=360-284\\ \\ 2y=76\\ \\ y=38 \end{gathered}$

The value of x is 33º, the value of y is 38º and the value of z is 109º.

WILL GIVE BRAINLIEST IF CORRECT, IF WRONG NO BRAINLIEST Which statement accurately explains whether a reflection over the x-axis

Paladinen [302]

9514 1404 393

Answer:

No, A″C″B″ is located at A″(1, 1), C″(4, 3), and B″(1, 5)

Step-by-step explanation:

Line AB is horizontal, so reflection across the x-axis maps it to a horizontal line. Then rotation CCW by 90° maps it to a vertical line. The composition of transformations cannot map the figure to itself.

A reasonable explanation is the last one:

No, A″C″B″ is located at A″(1, 1), C″(4, 3), and B″(1, 5)
