Hi, I'm having trouble visualizing this problem. I cant seem to figure out where the measurements should be going.

"The longer sides of a triangular park measure 251.0m and 208.m respectively. The angle between the longest and shortest side is 56 degrees.

a) What is the angle between the shorter two sides of the park?

b) How long is the shortest side?

I cant seem where to figure out where the 56 degrees go. Between 251 and 208m or between 251 and "x"? From knowing that I'm quite sure I can figure out the problem.
