Can someone give me a hint on how to solve? Thanks...
A pyramid ABCDE has a rectangular base ABCD. Calculate the possible lengths of edge EC.
Dimension AB = CD = 35m
Dimension BC = AD = 18m
Dimension AE = 23m
What does the and mean?
It looks as if they were meant to be angles.
If angle ABE is 0deg38' and angle EBC is 0deg44min
then it is solvable.
Need a little more info.
Could you clarify the assumptions?
