The sum of the angles in a heptagon is 900°, so we would add the real numbers that we have here:

121°+139°+125°+126°+158°+120°=789°

x would equal the remaining value:

x=900-789

x=111°

The next correct step would be to open the absolute value signs. To do so, the equation would need to be put equal to two values wich both need to be solved to find the correct answers.

Equation 1: x-5=3
Equation 2: x-5=-3

The answers would be x=8 and x=2.

Answer:

x>-1

Step-by-step explanation:

Subtract 3 from each side

-2x+3-3 < 5-3

-2x < 2

Divide each side by -2

Remember that flips the inequality

-2x/-2 > 2/-2

x>-1
