Find the value of x<br><br><br><br><br><br> x=?
soldi70 [24.7K]

Answer:

x = 135 degrees

Step-by-step explanation:

For any simple n-gon, the sum of the interior angles is 180(n − 2) degrees. (n is the number of vertices)

180(6-2)=180(4)=720

the shape already has 2 90-degree angles, subtract both of those from total interior angle sum

720-90-90=540

the 4 angles left must make up 540 degrees

540/4=135

x=135 degrees

Find the equation of the horizontal line at a height of -3.9.
Sholpan [36]

The equation of the line will be y = -3.9, and the height after rounding off will be -4.

<h3>What is a straight line?</h3>

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

\rm m =\dfrac{y_2-y_1}{x_2-x_1}

The horizontal line can be defined as:

y = a

Where a is the constant.

Here a = -3.9

y = -3.9

The height = -3.9 ≈ -4

Thus, the equation of the line will be y = -3.9, and the height after rounding off will be -4.
