I feel really dumb asking this..but whatever
one length of the pgram is 7 the other is 9..the long diagonal is 14..whats the short diagonal
We will need Trignometry for this one . . . the Law of Cosines.
One side of the parallelogram is 7, the other is 9.
The long diagonal is 14.
What is the short diagonal?We have parallelogram with:Code:A 9 B * - - - - - - - - * / * / / * / 7/ * / 7 / * 14 / / * / * - - - - - - - - * D 9 C
. . and we want the length of diagonal
