if $vx = wz = 40\text{ cm}$ and $m\angle zvx = m\angle xwz = 22^\circ$, can $\delta vzx$ and $\delta wxz$ be proven congruent by sas? why or why not?

yes, along with the given information, $\overline{zx} \cong \overline{zx}$ by the reflexive property.
yes, the triangles are both obtuse.
no, the sides of the triangles intersect.
no, there is not enough information given.
