Question 1092227: AB and CD are two buildings which are next to each other. The height of AB is 50 m. The elevation of C from A and B are 50 degrees and 70 degrees respectively. Find the horizontal distance between two buildings. Then find the height of CD.
The sketch is a bit difficult to get, but thank you so much!

You can put this solution on YOUR website! .
I don't know why you use two letters to designate the buildings.
Probably, one letter stays for the bottom, while the other for the top.
Then, why do not say it directly and explicitly, "who is who" and who stands for what?
Second. The term "elevation" does not mean the angle. It means ELEVATION, which measures in the length units, not in degrees.
