Is Y=5 and Y=-1 consider parallel perpendicular or neither show your work please and asap

nexus9112 [7]

Answer:

parallel

Step-by-step explanation:

The "work" is to recognize that both equations describe horizontal lines. All horizontal lines on the Cartesian coordinate grid are parallel.

_____

<em>Additional comment</em>

y = constant . . . . . a horizontal line (y=0 is the x-axis)

x = constant . . . . . a vertical line (x=0 is the y-axis)

If you wanted to go to the trouble, you could compare the equation ...

y = constant

to the slope-intercept form ...

y = mx +b

Your comparison would note that m=0. That is, the slope is zero, so the line is horizontal. All lines with the same (zero) slope are parallel.

The measure of an exterior angle of a regular polygon is given below. Find the measure of an interior angle. Then find the numbe

FromTheMoon [43]

Answer:

Internal angle = $160^\circ$

Number of sides = 18

Step-by-step explanation:

Given that:

We have a regular polygon with number of sides unknown.

Measure of an exterior angle of the polygon = $20^\circ$

To find:

Measure of an interior angle and the number of sides of the polygon?

Solution:

Let us have a look at the relation of sum of external angles.

Sum of one internal angle and its corresponding external angle = $180^\circ$

Internal angle + external angle = $180^\circ$

Internal angle = $180^\circ$ - $20^\circ$ = $160^\circ$

Sum of all the external of a regular polygon = $360^\circ$

All the external angles will be equal because it is a regular polygon.

Let the number of sides = $n$

Therefore,

$n \times 20^\circ = 360^\circ\\\Rightarrow n = 18$

Therefore, the answers are:

Internal angle = $160^\circ$

Number of sides = 18
