there are two Z's....one is the degrees the other is the length 39degrees...but i'm now guessing they want you to find the length...?

lol this question is worded so dumb...anyway since it's a right triangle we know
180 - 90 = 90 <-- the sum of Z + X
z = 39
so 90 - 39 = 51
x = 51 that is the length of 4 so therefore because Z is 39 degrees it has to be a smaller length, either: 3.2 or 1
