The value of the variable x is -17, and the measure of the labeled angle is -115°.
To find the value of the variable and the measure of each labeled angle:
Equating the expression x + 17 to 0 gives x = -17.
Substituting x = -17 into the expression 5x - 27 gives 5 * (-17) - 27 = -115.
Therefore, the value of the variable x is -17, and the measure of the labeled angle is -115°.
