Answer:
x = -4
Step-by-step explanation:
First lets add 82 + 55 which equals 137, then 137 +47 which equals 184
Now we know that a triangle equals 180 degrees (cannot go over 180), so this tells us x is a negitive number.
-x + 184 = 180
-x = -4
Another way to look at it is; 184 minus what equals 180? 4 does, so it translates into -4.
Each gets one and a half. :-)

Answer:
x = 7 x = -6
Step-by-step explanation:
x^2−x−42=0
Factor
What two numbers multiply to -42 and add to -1
-7*6 = -42
-7+6 = -1
(x-7) (x+6) =0
Using the zero product property
x-7 =0 x+6 =0
x = 7 x = -6
