Sqrt of 3 hope this helps
Chair height=c desk height=d (idk if its the chair that is taller or the desk but im guessing its the chair. if not you can switch the variables and it should still work)
d=29 3/4
c-d=-10 1/4
c=d-10 1/4
c=29 3/4 +10 1/4
c=40
1. x + 49 = -3x + 1
4x = -48
x = -12
2. 7x + 23 + 4x + 25 = 180
11x + 48 = 180
11x = 132
x = 12
