This is a vague description, so I’m assuming you have a triangle with two sides length 93 and 44. No angle is given so I assume a right angle. x is the length of the third side. That means Pythagoras’ Theorem. So x²=93²-44² or x²=93²+44².
Therefore we have x=√(93-44)(93+44)=√(49×137)=7√137=81.9329 approx, or x=√(8649+1936)=√10585=102.8834 approx.
