The answer depends on what you mean by cxd: there are several things that it could be an acronym for.
Cancelled is CXD
(axb)x(cxd)
It seems like "bv cxd" might be a typo or a shorthand for something specific. If you could provide more context or clarify what you're referring to, I'd be happy to help answer your question!
Supplementary angles.
axb + cxd
Given rectangle ABCD with X as the midpoint of AB, we know that angles in a rectangle are right angles. Since CXD is given as 118 degrees, we can find angle ADX. Since angles around point X must sum to 360 degrees, we have ( \angle ADX = 180 - \angle CXD = 180 - 118 = 62 ) degrees. Consequently, since ( \angle XCD ) is supplementary to ( \angle ADX ), ( \angle XCD = 180 - 62 = 118 ) degrees.

By rule of matrix multiplication the number of rows in the first matrix must equal the number of rows in the second matrix. If A is an axb matrix and B is a cxd matrix, then a = d. Then if BA is defined, then c = b. This means that B is not necessarily mxn, but must be nxm.
