It is indeed a right triangle. I checked. a^2 + b^2 = c^2.
So divide one side by the hypotenuse gives the sin of the angle. Look that up in a table.
So sin = 2/34.05877 = .058 Look that up in a table and it is about 3.5 degrees.
The sum on the angles equals 180 degrees.
So 180 - 90 - 3.5 = 86.5 degrees.
