  Function definition: (Copy & paste into FileMaker's Edit Custom Function window)

Use to calculate the angle of the vertex of an isosceles triangle if the lengths of the sides and base are already known. Output is in degrees, truncated at 10 decimal place of precision. No output if the base length is not less than the side lengths * 2 (otherwise it would be a line, not a triangle.)
