\(\angle ABC = 180 - y\)
Property: Exterior angle is the sum of opposite interior angles
\(\angle CAB = \angle ABC + \angle BCA\)
\(x = 180 - y + z\)
\(x + y = 180 + z\)
Therefore we need the value of z to find the value of x + y
Statement 1
x = y
Doesn't provide the value of z.
Hence not sufficient
Statement 2
z = 30
Sufficient, as we require the value of z and this statement provides the same.
