What is the value of x?

Dmitriy789 [7]

Answer:

C

Step-by-step explanation:

the sum of the exterior angles of a polygon = 360°

the exterior angle to 93° = 180° - 93° = 87°

summing the exterior angles and equating to 360

x + 52 + 87 + x + 3 + 78 = 360 , that is

2x + 220 = 360 ( subtract 220 from both sides )

2x = 140 ( divide both sides by 2 )

x = 70

Johan found that the equation –2|8 – x| – 6 = –12 had two possible solutions: x = 5 and x = –11. Which explains whether his solu

Effectus [21]

$-2|8-x|-6=-12 \ \ \ |\hbox{add 6} \\
-2|8-x|=-6 \ \ \ |\hbox{divide by (-2)} \\
|8-x|=3 \\
8-x=-3 \ \lor \ 8-x=3 \\
-x=-3-8 \ \lor \ -x=3-8 \\
-x=-11 \ \lor \ -x=-5 \\
x=11 \ \lor \ x=5 \\
\boxed{x=5 \hbox{ or } x=11}$

It should be x=11 instead of x=-11, so he is not correct because he made a sign error.
