No unique value for x; can be 1.2, 1.234. 6.9, 107894078.567 etc (infinite values). Is this a trick question or what?

This was a question from a yr 11 General Maths half yearly test. It had multiple choice answers, but I had no idea how to work it out.

It's an isosceles triangle. It does have infinite answers UNLESS you know one angle.
