1199.28856995
round 2 up to 3, because the next number is greater than 5 (which is 8)
I assume the equation is

then let
.


The right side is real-valued and positive, and only on the left side do we have an imaginary term, which tells us

Then




but again we omit the negative solution, so that

Answer:
6.3 mm
Step-by-step explanation:
The Pythagorean theorem tells you ...
c^2 = a^2 + b^2
Solving for "a", you get
a = √(c^2 -b^2)
a = √(8.3^2 -5.4^2) = √39.73
a ≈ 6.3 . . . . mm
The length of "a" is about 6.3 mm.
