Answer:
x = 135°
Step-by-step explanation:
6 sided polygon = hexagon
The sum of the interior angles of a hexagon = 720°
⇒ 4x + 90 + 90 = 720
⇒ 4x = 720 - 90 - 90
⇒ 4x = 540
⇒ x = 540 ÷ 4
⇒ x = 135°
 
        
             
        
        
        
Answer:
a)17.92
b) 16.83 .... 21.17 
Step-by-step explanation:
ρ→   z
0.14 =	-1.080319341
-1.080 = (x - 19)/1 = 17.92
~~~~~~~~~~~~~~~~~~
3% / 2 = 1.5%
1.5% - 98.5%
ρ→   z
0.015 =	-2.170090378 ....  -2.17 = (x-19) =16.83
0.985 =	2.170090378  ....   2.17 = (x-19) =21.17
 
        
             
        
        
        
A would be the most accurate choice. This is because the shading is above the parabola indicating it’s solutions are greater. And it’s not a positive parabola
