5z>15-----subtract 2 on both sides
z>3----divide by 5
therefore, z must equal -10, or -4

The two angles shown have the total measure 168°, so the unmarked one is ...
168° -100° = 68°
That is ∠WXZ, so we know ...
68° = (5x +38)°
30 = 5x . . . . . . . . . . divide by °, subtract 38
6 = x . . . . . . . . . . . . .divide by 5
