Four angles meet at a point and fill the space around it. Three of them measure 90 degrees, 90 degrees and 85 degrees. What does the fourth angle measure?

Explanation

The four angles use up one full turn, so the fourth is 360 minus 90 minus 90 minus 85, which comes to 95 degrees. Answering 85 degrees assumes the fourth angle has to copy the 85 degree angle, but nothing in the description makes those two a matching pair.
