Average value is the integral over time divided by the time period. This wave is sqrt(2)*sin(w*t)+10 amps. Taking the average yields 10 amps.
More intuitively, the average value of a sine wave is zero, so it neither adds nor subtracts from the constant DC component.
Note the rms value would be different.
