Parallel lines g and h are cut by a transversal k at points R (on g) and S (on h). At R, the angle on the lower right of k is (4z+14)∘, and the angle on the upper right of k at the same point is 62∘. The angle on the lower left of k at S is corresponding to the 62∘ angle at R. Determine z.
a) 12
b) 32
c) 26
d) 23
