Hey! You just have to square root the 2 and 5 then multiply by 11 so the answer I came up with is 34.78505426185218
I hope I helped!
3x - 14 = 2x + 25
+14 +14
3x = 2x + 39
-2x -2x
x= 39
therefore x is 39. If you want to find the exact angel, just substitute 39 into x, solve for it and it should give you the exact angel.
Hope I helped :)
