In order to find the equation that will solve for x, we need to use the fact that the sum of angles in a straight line is 180 degrees.
Angle 5, which measures 112 degrees, is supplementary to angle 8. Therefore, angle 8 must measure 180 - 112 = 68 degrees.
Now, we can set up the equation:
68° + (2x + 8)° = 180°
m∠5=112° and m∠8=(2x+8)° . What equation will solve for x ? (2 points)
