In a bicyclic cycloalkane derivative with two methyl substituents, one on each of the fused rings, determine the correct cis or trans configuration if one methyl is on the equatorial plane of one ring and the other is axial on the adjacent ring. Which configuration is represented?

In a fused bicyclic cycloalkane, an equatorial substituent on one ring points roughly outward from that ring, while an axial substituent on the adjacent ring points roughly inward on the opposite face. Because the two rings share a common bond, the outward direction of the equatorial methyl is on the same side of the bicyclic framework as the inward direction of the axial methyl, placing the two groups on opposite sides of the skeleton. This opposite‑face arrangement is defined as the trans configuration. For example, in bicyclo[2. 2.
