There's an infinite amount of solutions

Any x and y that satisfy this will work

I can't get any more equations than this one other than redundant ones

This is how I (OP) worked it out when it was posted on /b/ But I only did GCSE math and haven't done any real math problem in about 5 years.

The right is the order I did it in, I had to guess the pink block colour angle and guessed the rest of the block colour angles to get a solution but guessed 70 to start with which gave me a solution first try, however I do believe there are probably multiple solutions.

Holy shit I wasted about an hour on this when it was actually so fucking simple. This is why math should be left to experts, people could get hurt.

You're wrong, it's 20.

All the other angles are fixed, x and y can't vary without changing the others. Use sin and cosine rules.

Just worked it out. This is exactly what I got
