To find the angle of vertex E,we need to first find the sum of interior polygons to determine x:

In this case,the equation would be:
(7-2)×180°
=5×180°
=900°
We can then find the value of x:
(4)6x+(2)2x+8x=900°
24x+4x+8x=900°
36x=900°
x=25°
The interior angle of vertex E:
6x=6(25)=150°
Therefore,the interior angle of vertex E is 150°.
Hope it helps!
B)
así que si usted toma el número sesenta dos entonces se obtiene cuarenta y seis
5x +2 =4x
subtract 2 from each side
5x= 4x-2
subtract 4x from each side
x = -2
It is 40 40. 40 is the answer
