Answer:

        1  

= -----------

   6(x + 7)

Step-by-step explanation:

3x - 21      x^2 - 49

----------- ÷ -------------

18x - 18        x - 1

3x - 21          x - 1

----------- ×  -------------

18x - 18       x^2 - 49

Factor the top left:

3x - 21  = 3(x - 7)

Factor the bottom left:

18x - 18 = 18(x - 1)

Factor the new bottom right:

x^2 - 49 = (x + 7)(x - 7)

Multiply and simplify the faction:

3(x - 7)            x - 1

----------- ×  -----------------

18(x - 1)       (x + 7)(x - 7)

        1  

= -------------

Find the measure of exterior angle A. Show equations and all work that leads to your answer.
Morgarella [4.7K]
Fine but I ain't showing my work completely.

The sum of all ext. angles of a polygon = 360.

So, you make this formula and solve for x.

360 = 49 + (3x+30) + (14x+6) + (6x-3) + (4x+8)
360 = 49 + 27x  + 30 + 6 -3 + 8
360 = 90 + 27x
270 = 27x
/27      /27
  10 = x

Now substitute for angle A, which is (6x-3)
6x-3
6(10)-3
60-3
57

Therefore, angle A is 57 degrees.
