Respuesta :

Angle Z is on a straight line, along with the angle measured 124°. Because we know that angles on a straight line add up to 180°, we can say that 180 - 124 = z, so 180 - 124 = 56°, which is your answer.

I hope this helps!

Supplementary angles are 180 degrees then subtract that from 124
Hope this helps!!
