+617 Let $WXYZ$ be a trapezoid with bases $\overline{XY}$ and $\overline{WZ}$. In this trapezoid, $\angle ZXW = 120^\circ$, $\angle XWZ = 60^\circ$, and $\angle XYZ = 120^\circ$. Find $\angle YXZ$, in degrees.
+1790 If angle XWZ = 60°, angle WXY = 180° - 60° = 120° because XY and WZ are parallels.
However, this means that Angle ZXW must be less than 120°.
In the problem though, it clearly defines ZXW as 120, meaning this problem is invalid.
Thanks! :)
