its a sqaure so the angles are 90 degress each.

90 - 38 = 52

C. 52

c = 52*

Step-by-step explanation:

If we assume that both shaded triangles are equivalent, and we know that the total angle of a square's corner is 90*, to find the missing angles of the unshaded area (angle z) we just subtract 38 from 90.

90 - 38 = 52*.
