Find the value of x. Using the picture
SVEN [57.7K]

Answer:

x = 23°

Step-by-step explanation:

  • The figure given below is an irregular polygon with 7 sides
  • The polygon is therefore an irregular heptagon.

We are required to determine the value of x

  • We know the sum interior angles of a polygon is given by;
  • Sum of interior angles = (n-2) 180 , where n is the number of sides

Therefore, in this case;

Sum of interior angles = (7 - 2 ) 180

                                     = 900°

Hence;

7x° + 2x° + 8x° + 60° + 10x° + 8x° + 35° = 900°

35x° + 95° = 900°

35x° = 805°

    x = 23°

Thus, the value of x is 23°

What is the slope of the line that passes through the points (4, -6) and (4, -2)?
katen-ka-za [31]

Answer:

undefined

Step-by-step explanation:

Since we have two points we can use the slope formula

m = (y2-y1)/(x2-x1)

   = (-2--6)/(4-4)

   = (-2+6) / 0

We cannot divide by 0 so the slope is undefined

15.42 = 15.42

40/8 = 6

40/8 ≠ 6
