Respuesta :

well we know a flat line is 180 degrees, and if I'm doing this correctly...
180 - 124 = 56
56 is an acute angle, and that's just what z is!

Hope this helps, I am not totally sure how to do it but I think that's how.
Here, sum of z and 124 would be 180 as they are supplementary angles.
i.e., z + 124 = 180
z = 180 - 124
z = 56

In short, Your Answer would be 56

Hope this helps!
