I agree with your solution.
Two strips of cloth with width 1 overlap at an angle a as shown. Find the area of the overlap.
I swear I am missing something on this.
Rhombus Area is base x height
Height is 1
Let base = x
unknown angle a
So all I could come up with was:
Which gave me the Area = A
I don't recall ever figuring out an area with so little information given before.
Hello, brokaliv!
If you submitted the answer to an online exam,

You are saying, "Hey, I did all the algebra!"
